Garmin or Fitbit

Posted on by Gilbert Van Kerckhove

Tests done and concluded

Should I go for Garmin or Fitbit? As mentioned earlier, I wanted to give the Garmin Vivosport GPS a second chance.
During several days I used both Garmin (left hand) and Fitbit (right hand), comparing each morning the data.
Garmin has indeed improved its software and the sleep tracking is totally updated.
My final choice is … the Fitbit Alta HR. The Garmin is back in the box; if the Fitbit dies, I might still use it.
The choice is very personal, for some the Garmin could still be the first choice.
See here the details.

Three series of tests

See the different screenshots of the Garmin and Fitbit for 3 dates: 29 July, 30 July, 31 July.

Sleep tracking

The Fitbit is very sensitive and often counts as “awake” when I am actually sleeping. But I can check the details and I usually add like at least half of the “awake” to the sleep total. The advantage of the Fitbit: great detail and pretty accurate for sleep start and sleep end. The Garmin does record “awake” and is overall much less sensitive. Start and stop are however not always right: if I wake up and stay in bed to check my mobile, for Garmin that is still “bedtime”, not for Fitbit.
I also like more the overview of the days for the sleep tracking.
As sleep tracking is for me the focus, Fitbit wins.

See as example for reading on 29 July:

Fitbit: start 00:24 – stop 08:03; asleep 6H40 and awake 59 min, so that is some 7H20 sleep for me
Garmin: asleep 7H57 (no start stop in the pics)

And for reading on 31 July:

Fitbit: start 23:03 – stop 06:54; asleep 7Hr9 awake 42 min so total sleep for me like 7H30
Garmin: start 23:14 – stop 07:22 (wrong!) asleep 8H6 – awake 2 min

Stairs climbed

I am interested in this reading but as said earlier, Garmin totally under-reports, so useless. I do a lot of stairs…

Steps

See readings 30 July:

Fitbit 7,016 steps
Garmin 4,232 steps.

Why the big difference, no idea. I do trust more the Fitbit readings.
Fitbit gives a clear overview on many days for the steps; Garmin does not, you need to check day by day.
Fitbit wins here for me.

Resting heart rate and heart rate

Fitbit gives a much more clear overview for the past days of the resting heart rate and it allows you easily to check heart rate for every day, in detail.
Garmin does not give a good overview, one needs to check day by day. The only advantage (not important for me): it show record for cycling. Fitbit is not really reliable for cycling (my rides are also pretty short).

Conclusion

For some users the many sophisticated features of Garmin, such as to track cycling (using the GPS) and other activities might appeal. As I usually do short bike rides, switching on and off the GPS is too much trouble.
For me the focus remains with sleep and resting heart rate.
Thus Fitbit it is…

From Garmin to Fitbit again

Posted on by Gilbert Van Kerckhove

Looking for the “best”

How I went from Garmin to Fitbit again…
As I was totally disappointed by Fitbit, I thought this time I would do some research and chose the best and most suitable health band for me; little did I know it would end up with Fitbit again!

After a lot of googling, the choice fell on the Garmin Vivosport GPS. So I thought I was clever.
The Garmin was  RMB 1299 and I registered the band on 20 June 2018.
It took quite some efforts to understand and use the many features, I could even register my bike ride, check the time and distance etc. Well, all a bit too complicated for me, as my rides are rather modest.

Website horrors

The same horrors with the Garmin websites, as with Fitbit. As I am normally either on a Chinese, Korean or Japanese IP address, all came only in those languages with no way to change the language and country. Also as a result, totally erratic registration and password issues. Actually when I tried now to use the Garmin again, password did work on a Belgian server but not in China. What a mess. I was forced to re-register the band (yeah with another email address because this they apparently knew about the other one used). All from scratch. A real ordeal.

Sleep tracker not working

The Garmin Vivosport is a great tool to track your fitness, exercises, biking, … Even a bit too complex and complicated for my taste, but surely impressive.

But my major focus is on sleep tracking as well as resting heart rate, heart rate, among other. As I found out soon, sleep tracking was a major problem with Garmin, it fails to correctly monitor your sleep. It seems that the software was not working properly, as I found out in the many discussion forums complaining about it. And a solution was apparently not to be expected anytime soon.
For me, the Vivosport was a total disappointment and I stopped using it.
Right now as mentioned, I took the Garmin again out of the box to see if the problem remains.

Back to Fitbit

In life never say never. With the total disappointment of Garmin, new search.
So I settled for the Fitbit Alta HR, cost in promotion RMB 988.
The band is really simple but meets exactly my main requirements: Sleep monitoring, resting heart rate, and less relevant for me step counting (because I bike every day and that does not register). The only feature I miss is counting stairs (I do quite a lot…).

 

I did then the tests with both Vivosport and the Alta, each on a different arm. Results were pretty obvious, as you can see in the pics dated 2 August 2018 and 5 October 2018. The Vivosport is totally wrong and for no apparent reason.
Overall the Alta is rather correct for sleep monitoring, while the Alta often marks some sleep as “awake”. But this I can check easily: registered “sleep” 7 hours and “awake 1 hour: so I know real sleep was close to 8 hours if I know I did not get up in the middle of the night. It also does register an afternoon nap if it is at least close to one hour.

More testing

After some frustrating trial and error, a new registration, the Vivosport is working again. Still some issues remain. Now comparing, one on each hand, the first readings:

 

Still further improving settings on the Garmin, not easy. Work in progress.
It seems Garmin did improve the software.

Stairs climbed

As for stairs climbed, the band is totally underreporting, yesterday I climbed close to 30 floors but it barely registered. That seems to be an issue with most bands. Doing a search it seems many people complain about this.

Says Garmin:
Your device uses an internal barometer to measure elevation changes as you climb floors. A floor climbed is equal to 3 m. Locate the small barometer holes on the back of the device, near the charging contacts, and clean the area around the charging contacts. The barometer performance may be affected if the barometer holes are obstructed. You can rinse the device with water to clean the area. After cleaning, allow the device to dry completely.
In my case I found one small hole only and on the other side of the charging contacts. Maybe because my model is older?

I will test for a few days and report back!

Fitbit Charge HR

Posted on by Gilbert Van Kerckhove

A symbol of bad quality

On 19 June 2016 I got a Fitbit Charge HR after using a modest health band version of Xiaomi. Price was RMB 758.
It was the start of never-ending breakdowns.
The top of the band was peeling off. Then later the band broke underneath near the reader unit. I used it daily but I was careful. Quality was plain horrible, it is a fitness band and should resist normal use.
I soon discovered everybody had the same issues and the discussion groups showed endless complains, all about the same.

Repairing

I did try to repair to put back the band (top side) and the broken band (underneath near the reader). Super glue worked but it would never last.
See the pics, look at the bubble on the armband and the broken connection underneath.

 

I did finally succeed to contact the company and they sent a replacement: not just the band but a complete new unit. It seems for some models you could change the band with a hexagonal wrench but in my case that did not seem to work. I also don’t have that VERY small wrench…
Looking at the flood of complaints, it was clearly a manufacturing and design flaw that was never addressed properly, totally ignored by the company.

A new unit

After my complaint I did receive a new unit, in February 2017. When the electronics died (another poor quality issue) in the first unit, I then used the new one on 18 February 2018.
Sadly the new unit also did not last long. The electronics died. See the Fitbits ready for the garbage bin.
That was the end of Fitbit for me and I said I would never buy a Fitbit again. The horrible handling by the management of that defect was really a shame for the company. They would simply ship the same rubbish as a replacement…

With the flood of complaints, Fitbit closed the help forums related to “Charge HR Band Delamination Problems” and related:

SantiFitbit (Moderator) posted a new reply in Problems with Fitbit Charge and Charge HR bands on 11 June 2018.
Hello everyone! Thanks for your participation on this thread regarding the Fitbit Charge HR bands.  It seems that the conversation on this thread has jumped to multiple topics so I will be closing it to keep this board on topic.

But for me, the story with Fitbit did not end there…
More to follow!

Fitbit website, one of those retarded sites

The FitBit websites are a pain, in Beijing I can only see Chinese, if I am on Japanese server, all Japanese and no clear way to switch to English. So I had to switch my VPN to a USA server.

I guess Americans must think people never travel. You are supposed only to visit their websites when you are in your “home country”, whatever that means. So if you are visiting another country, you have no more access to the website.

Talking about shortsightedness in the 21st century. Worse, as it is the case for many of those websites, there is no clear link to switch the language and the country. Sadly to say, Google is one of the retarded in that aspect. They all blindly look at your IP address from where you go on the Internet, and trying to change the “country” is mostly unsuccessful. Good we have VPN to fool them.

Chinese air purifying machines

Chinese air purifying machines: many “choices”

I never buy a Chinese air purifying machine but sometimes we get them as a present. I also tested the cheap Xiaomi machine in a friend’s house (cost: something like under 900 RMB).
The machines we really use are IQAir and AMWAY.

Testing

Yesterday we got a new machine, the “ZB-801” (no English name found). As the pollution levels were climbing we decided to open the box and see what it could achieve. Inside the house we had AQI around 220, using the excellent LaserEgg from Origins.
I decided to test the two Chinese air purifying machines. Well, results were worse than expected.

The ZB-801 delivered air at just above AQI 150. Also that machine is not user-friendly as it always switches off instead of working constantly.
The older machine, a brand called DEERMA, was even worse, delivering AQI above 160.  Their slogan “The best choice for your healthy breath” is obviously a sick joke.
The test with the Swiss-made IQAir showed the real thing: the output went immediately down to 4, which actually is zero according to Origins.

So, if you need a machine against the Beijing pollution, buy a LaserEgg to check the real condition (and adjust the speed) and a quality machine such as IQAir, AMWAY, BlueAir and alike.
Throw out the Chinese junk.

The cheap Xiaomi: it seemed actually to perform a bit better, delivering AQI below 50. But is is suitable for small spaces only and cannot constantly work at its higher speed.
I guess using a big fan with a good HEPA filter taped to it is better and cheaper.
The Chinese consumer industry has a long way to go…
