Honestly, almost as soon as I ordered these watches for my man & me, I thought I was going to send them back. I didn't have much confidence at all that I was going to like them! However, I've been pleasantly surprised! While they're not the MOST accurate smartwatch on the market, if you go into ownership of this watch knowing that, you won't be disappointed either!Full disclosure - I use the data on this watch as a guide ONLY! I do NOT have any medical conditions that require constant, accurate monitoring of ANY of the vital signs advertised for this watch. I primarily use the Step Count feature for biofeedback. I find that it DOES motivate me to find ways to take extra steps throughout the day.At some point, I admit that I will most likely purchase a Samsung Smart Watch (I loathe Apple products, so I will NOT purchase Apple ANYTHING!) This device has given me an idea of what to expect with a Smart Watch.I'm not thrilled with the fact that the band on this watch is NOT replaceable. The graphics on the watch face exceeded expectations (I had expected them to be far less sophisticated). The app is passable, but obviously NOT written in English by a native English speaker.Bottom Line - If you purchase this item with appropriate expectations, you won't be disappointed. It's NOT an Apple or a Samsung Smart Watch, but it IS a decent introduction to these types of items. Just as a further FYI - NO Smart Watch is designed for prolonged periods in water! Electronics & water NEVER mix, regardless of "certifications".

I have been using this watch for a week and I love the features. The 42mm size is perfect for my wrists and it doesn't look like a smart watch because it is not real bulky. Even the smaller size it still is easy to read. It works great with my Samsung S9 smart phone and the Samsung wear app on my phone makes setting up and changing settings through the phone very easy. Battery life seems to be fine, used it a lot yesterday and when I took it off last night to charge it was only down to 65%, so it should work fine for at least two days. The only negative is the silicon band that comes with the watch is OK for sport use but I wanted a better looking band so I purchased a leather band for $15 on Amazon that looks great and fit perfect.

I like the watch just can't find a screen protector to fit it

I’ve had this for a couple months now, perfect watch for the active and fit.

I was sooo excited to recieve my NIUDOKK Smart Watch for Christmas!! It is exactly as I imagined! Now, I can keep up with my Steps, Check My Blood Pressure, Check The Weather & Recieve Text Messages etc.!!! I am seriously considering gifting my husband a NUIDOKK Smart Watch to help him monitor his Health as well the gentle reminders to drink more water!!

this watch does everything, accurate responsive and easy to read.

Looks great and looks like an Apple Watch. Easy to use and has great battery life.

Love everything about this smart watch. It fits (have a small wrist) and I love everything it tracks. Also, easy to set up!!!
