SMA-Q2 Heart Rate Smart Watch,IP67 Waterproof Fitness Tracker,Acivity Tracking Watches for iPhones and Android,Gift for Women Men,Black

Love it. I have about five "fitness watches" and this is the one I wear.Display is "always readable" LCD.You don't have to push a button and its readable in sunlight.Really does have 40 day battery life (well, maybe thirty).I run it with it auto sampling pulse every 15 minutes.It does a pretty good job. Some way off readings.All readings are, curiously 5 points high.Several different watch faces, though most are dumb.I wish the default one showed day of week, not just date.App is ok (iOS). Sometimes I need to turn BT on my phone off/on to get it to reconnect if it's been away from phone.Anyway, wear it every day!

I purchased this watch because had large digit display and heart monitor and was water resistant. But I had to return it because the right top buttons got stock couple of times after few days and kept toggeling the screen rapidly. Also Initially the watch's bluetooth synced fine with my Android phone, but after few days what ever I did I could not sync it by even setting my phone to forget the device and search again for the watch device, even trying to update the App, and believe me I had installed the right SMA app, because initially it worked.The third major issue is that some of the important functions that is listed on the advertisment for this SMA watch is only controlable by the app while it is synced with your Mobilephone, not through the watch's controls and that is misleading advertisment definition that through the watch user can control everything like other watches in this category can.In conclusion, since this SMA watch is not touch screen and only controlled by the buttons or the app on the phone, and then both the stuck buttons and the app not syncing is a major problem, I would say this watch is of no use. The seller needs to do major quality control before selling watches on Amazon.

Inexpensive but equal in performance to the many more expensive smartwatches I own (seven in total). Excellent sleep tracker, better than others costing far more. Very visible screen in daylight. Well worth the cost!

Excellent watch, does everything I need it to. I am a supervisor in construction and around loud noise all the time. Before the watch I would miss important calls or texts, because I could not hear my phone on my side. The only draw back is I can't get it to let me know when I get a email from our server. G mail works. I recommend this.

Returned, because wasn't what my husband wanted.

As advertised worked well

Returned it. watch was fair quality but the apps/ software are as if my son had written the code. A lot of compatibility issues if you plan on using downloaded faces.

This is awesome, and worth to pay that money for this SW.

Strap broke in no time and screen cracked when it should not have.

Horrible! Broke within two weeks.

That's all

I got the watch and the screen was scratched, the heart rate monitor was dirty and also had scratches on it. The instructions were in Chinese, the band didn't fit.

Does not work right

band is flimsy

Says "Swimming Waterproof" but after swimming read the detail paper work states not to swim with it. I bought it for the purpose of swimming with it.
