Kummel Fitness Tracker with Heart Monitor

This inexpensive little guy survived the washer and dryer. I was highly impressed. The battery lasts a few days to a week but I don’t wear it all the time so it might last even longer if it’s not trying to find you when you’re not wearing it. (The back, the part thats against your skin, annoyingly flashes green when I’m trying to sleep without it on) The step counter is fairly accurate, it only occasionally misses a few steps I take. The screen is clear, simple, and easy to read. There aren’t a ton of features, which was a plus for me because I wanted something simple. It’s lasted me longer than I expected for the price. I have found I need to reconnect it to my phone through the app every few weeks to keep the clock accurate, otherwise it’s about a minute or 2 slow. Works great otherwise, handy device

I really loved this product for about five weeks. It was awesome. I was tracking my workouts and my sleep. I get between 10 and 20,000 steps in a day for a few days a week from work and another 5k on days I work out.

I also track my sleep, which worked okay at night, but not so much during the day (I sometimes work overnight and sleep during the day). I track all of this in their app and send the info to Google Fit.

On the sixth week, I notice that after walking about 10000 steps, it recorded 0. I tried every troubleshooting step. I cleared the app cache and data. Made sure the app was updated, made sure that the firmware was up to date. I rebooted the device from the app about a dozen times. I let the device battery drain to zero then I charged it. I rebooted it multiple times.

Nothing worked. If it tracked any steps it may track 10% of it. When you take 10k steps and you only see 1000… I was disappointed.

I really want to love this product, but either the firmware is broken or the device is broken. This is way too soon to be broken from wear and tear.

If you look at all the one star reviews you will notice a pattern. After about a month to a month and a half the device will stop working. This is extraordinarily consistent. This review should be posted at the top of the reviews to let every person who is thinking about buying this product no that the device will absolutely stop working within 2 months of purchase.

I like the band, I like how it charges, I like how it looks, I like how it fits. It seems quite accurate.

The app is terrible. First of all, it starts with an ad for a product that I am not interested in. And regardless, what app for a product that you bought is ad based? This is reprehensible.

Second, it doesn’t have my desired features. . I have not yet found a way to add steps that I know I took when I had the band off. This is a simple thing to do in the Fitbit app but not in this app.

Third, it’s difficult to find anything in the app. Everything is hidden. For example, you have to go to a sublist to find the amount of battery you have left, it’s not displayed when you pull down to synchronize. It should be on every main display of the band. You shouldn’t have to choose between seeing your steps and the time and seeing the battery power. I want to see all three, and there is no way to see the battery power on the band while you’re wearing it unless you choose that display and don’t see the steps on the main display. Bad use of space.

I was able to get rid of the green flashing lights when I’m not wearing the band by turning off wrist sense. But that’s a stupid workaround. It should possibly flash a couple lights, more slowly than it does, and then only do it once when you have wrist sense on, and are not wearing the band. Instead of doing it very fast, like a flickering light, repeatedly with no end. I think the very fast flash is dangerous (if you happen to be epileptic, or be around someone who is), and it’s annoying to those to whom it is not dangerous. I’ve seen someone go into epileptic seizures as a result of flashing lights from a fire alarm. It’s not a good thing. You would think the company would see this coming as a lawsuit.

So, my mixed feelings lead me to a three star rating. This software engineers and the management have ruined a good effort by the hardware engineers.

At this price point it’s pretty much everything you could ask for.I’m skeptical of the durability of the band/charging port but time will tell. Easy enough to install the app, customize it to account for stride and other things to assist in accuracy. Battery usage seems good so far.
It misses counting some steps sometimes but does pretty good. Easy enough to navigate and takes a minute to figure out the finer points but you’ll catch on pretty quick. For the price point I’m very happy so far. Can’t vouch for the sleep tracking really but it’s fun to have available and appears accurate enough.
Edit 2/13/23: After living with it for awhile my big complaint is it is useless in the light even on pretty cloudy days. Covering it with your hand doesn’t help much. I still like it overall but as a real time tool not much good unless you exercise indoors since you can’t view it outdoors. Not sure what the fix is as cellphones aren’t a lot better in daylight.
