The following was written by my husband as I purchased these at his request.
We bought 2 of these watches (wife and I) expecting them to be a “throw away” devices and we were not far off the mark. I recently had to start heart training and am a total beginner to the market. With that in mind, I thought I would save others some research by sharing my findings.
I’d like to start with the dilemma I had no idea existed until I bought this watch; ALL fitness watches in 2022 have trouble providing accurate heart rate numbers for people with tattoos, dark skin, or excessive fat where the device is placed. I found this out firsthand when I couldn’t get a heart rate reading for the first day and a half with this device. Once I switched to the underside of my wrist where I don’t have tattoos, my problems with having a flatlining pulse disappeared.
I’ve noticed several deficits with this device over my 2+ week trial. The biggest of these is the ridiculous battery life. I had an average of a day and a half between fully charged and completely drained. This was after I moved to the clean skin on the underside of my wrist, so it was not because the device was trying to find a signal through ink. Additionally, I only allowed the permissions to run Bluetooth while the app was running and I closed the app when I wasn’t actively monitoring, which was about 4 times a day. This tells me the battery discharge was not due to overactive Bluetooth pinging.
Another problem is the consistency of the data. As you can see from the attached screenshots, I ran a side-by-side comparison of my workout data over the first 3 days of March. Each of these days followed my activity during 25-minute Beachbody T25 workouts. I have been wearing a polar chest strap for about a month and have correlated the data it provides several times with manual checks. This watch typically cheats me in my heart training at a rate of 20-30 bpm compared to the chest strap. The only advantage the watch had over the strap was on “Ab Day” when I was skewing the chest measurements with movement. The watch showed comparable peaks and valleys to match how hard I was working through the workout, but with the numbers so far off, I would have no idea if my workouts were getting the job done just relying on the watch alone.
Finally, I also must agree on the complaint about the size of the wrist strap. Mine fit just fine but I have embarrassingly small wrists for a man. I can comfortably wear the watch using the second from last hole and still get a good reading from the heart monitor.
On the plus side, this watch showed me that the technology is something I would use so I have already ordered a replacement. I don’t feel I got my money’s worth out of it, but it did help me make a smarter decision in my replacement purchase.
Pros: Very cheap compared to others in the market, sleek looking, multiple display faces, lots of features to play with, sedentary alarm gets your attention, find my phone option is neat (although doesn’t work if the Bluetooth or sound is turned off), pairs well with Android, OK interface and reporting, syncs with Google Fit
Cons: Crappy battery life, inaccurate heart rate monitoring, small and proprietary watch strap (can’t buy replacements or get bigger), bulky if you need to wear on underside of wrist, and hard to hide if you have tight long sleeves.
Overall I gave 3 stars because I wasn’t expecting much. I took 1 star off for the battery life and 1 star off for the very inaccurate monitoring.
