I bought this watch at a sale price of around $50, and feel that was fair. This is my first watch that allows me to make phone calls, and I had difficulty connecting the two devices. However Taryn G wrote a review which gave instructions on how to do this, and once I followed those, pairing the two was not difficult. It would be nice if the manufacturer would supply clear instructions written large enough to actually read.
That being said, I'm pleased with the purchase. These are things to keep in mind:
Several watch faces are included in the purchase price. Others are available for between $.49 and $.97 apiece. I bought two of these.. You are allowed to make one custom watch face at a time. During the day, this is the face I use most frequently. I uploaded an image from Pixar Bay, but some people might want to use a photo of a loved one. One thing I would like to see in future products is the ability to create at least three custom watch faces at a time.
I have used the sleep option for about a week and I would say it is reasonably accurate. However if you get up in the night for an extended period, that will end the sleep session, even if you go back to bed. Short breaks to get up to use the bathroom or not a problem. It also seems to register laying in bed and being unable to sleep as "light sleep."
I haven't used the workout features, only the steps. so I can't comment on those.
On my device, the heart rate and oxygen levels seem fairly accurate. Others have reported inaccuracies. I wonder if some of that depends on how tightly you apply the band. Mine is just loose enough to slide one finger under it with a little pressure.
To access settings, you swipe down from the top of the watch face (while the clock is displayed) and select the settings icon here you can adjust sounds, brightness, etc. There is another menu which displays when you press the watch button while the clock face is displayed. From this menu you can set a stopwatch or a timer.
There is a slight delay of a second or two for the watch face to appear when you "raise your arm." However the instruction to raise your arm does not work. It actually refers to the twisting motion your arm makes when you're looking at your watch, which turns the bottom of the watch face toward the ground. That is a little difficult to get used to at first, but after a couple days you adapt.
Overall I am very happy with the watch and again think the price was fair. The watchband is plastic, which is the biggest factor that reduces the expected price. With plastic bands you must wash them every day to prevent odors from building up from bacteria trapped between your arm and the band.
