michiaki 3 This is my 3rd smartwatch & I chose this for the extra features like blood oxygen among other health related features. So far, excellent touchscreen function to immediately check directly rather than have to go to the app for the same thing. Given the price, I was worried it may not work as well as stated & of course, measurements are not medical grade accurate, however good for reference. The strap is soft & flexible enough though a little snug at the buckle point but the little tab to insert into the strap holes is a good idea for a stopper so it stays fixed in position. I would have highly recommend it but after 1 week's use, not happy with the step counter. Suggestion - may be a good idea to have extra straps in various colors/designs to give a choice/option as black is basically just serviceable but boring.After 1 week of use, found that the step counter is wildly inaccurate. Standing in place with vigorous arm movements showed counted steps. Checked watch, walked 70 steps but no data shown after that. Comapred with actual pedometer, the steps counted had a huge difference. Not sure if this is because of any defect but if so, I hope the seller will take necessary action to replace it.
