ZKSSGY Fitness Tracker with 24/7 Heart Rate Blood Oxygen Sleep Monitor,Activity Tracker with 1.1" AMOLED Touch Color Screen, Multiple Sport Modes Step Counter,IP68 Waterproof for Women Men (Wine Red)

I love this tracker, and I've tried several. It arrived the next day, charged quickly, was super easy to set up, and it's been a week since I charged it - still going strong. The FitBit I bought in February was losing a charge in three days, the first replacement I got ($50) did the same, so I was skeptical of a $28 tracker being effective. Fitbit also failed to track sleep accurately when I slept on one side, so consistently said I got about four hours sleep - this one gets it right. I'm seriously ready to buy at least one more. I also have a small wrist, so I appreciate the sleek size and attractive appearance. Highly recommend.

Great value for the price. Cute watch that works better than expected. Easy to connect to Bluetooth. Features such as steps and heart rate seem accurate so far.

This is a nice little watch. I like the color and it is comfortable (which says a lot because I don’t like wearing watches.) However, I have doubts about its accuracy. I walk the same route every day. I have confirmed that it is a 3.5 mile loop. Yesterday I walked the loop and the watch tracked my steps as over 10,000. Today I walked the same loop and it tracked my steps as 4342. I am going to keep it to see if it is operator error, but….I also do not put any faith in its accuracy measuring heart rate and blood pressure. I have read that if your arms move too much, it could give false readings. Not sure how this helps a device that is supposed to track movement.

So far I love this tracker! I didn't want to spend the Fitbit price or the apple watch price or Garmin. I just wanted something to track some health gauges and aspects of my life. This works fairly well with the BP and RHB only off slightly compared to a regular monitor so you can bet your numbers are near what you see on the app. The app is a little confusing since for calories it says consume but I think it means burned based on your activity? So far no problem with the durability I think that it's hardy and will last. All this to say the price was great and the reviews were spot on. I'd buy it again!

bought this mainly to count my steps and was surprised by how much useful data it provides. The step tracking is accurate and updates in real time, which helps me stay active throughout the day. What really impressed me is the sleep report. It shows light, deep, and REM sleep cycles and the REM data helps me understand how well my body and mind recover overnight. I noticed clear patterns between my bedtime routine and how much restorative sleep I get. Also tge app is free so it’s a good deal

This tracker is such a disappointment. Based on the activity, it's anywhere from 50-100 steps below the steps completed. This is a replacement for a tracker just like this that I've had for 1.5 years. The tracker worked beautifully, but the band broke. That tracker was only off by a few steps when working out. This tracker is unbelievably inaccurate. The sleep mode is joke. The 1st night I wore it, I went to bed at midnight. I awoke at 6:25 am. The tracker showed I slept nearly 8 hours. I thought this was a fluke. But, no. It always shows I slept more than I actually have, even though the time I went to bed and the time I wake up is showing as accurate. I also have doubts about the accuracy of the breakdown of the sleep cycles. As for the blood pressure readings, this are way off. The systolic pressure is usually 20 points off. The diastolic pressure is 15+ points off. I have a home blood pressure monitor, which is very accurate. I check the tracker after using the monitor to compare readings and find it to be inaccurate 100% of the time. If you're someone who needs to monitor your blood pressure and pulse, it would be dangerous to your health to rely on this tracker's readings. Don't waste your money on this tracker. The only thing accurate about it is the time. Additional Comment: The longer I have this so called tracker, the more inaccurate it has become. I do some sort of exercise in the morning and usually once again later in the day to break things up. Problem is, the tracker won't fully track anything beyond the first workout. Today, for example, I worked out for 25 minutes this morning. I just completed a 30 minute cardio session. Before I started the 2nd session, I set up the workout mode on the tracker. When I completed the session and stopped the workout mode, it showed that I worked out for a total of 4 minutes and took 90 steps. There's no way to manually change or add a workout session, as there is on a Fitbit. This isn't a tracker or a health monitor. It's just a watch. It offers nothing but time and false advertising from the company that created it. Don't waste your money.

I’ve been wearing it a month and I’m happy with the way it works. My Fitbit worked the same way, but the feature it had that I liked was that you could set the time that you go to bed and wake up. This product does not allow you to do that. You have to split days to see

The reason for the 2 stars was it keeps good time but the blood pressure, heart rate, temperature, step count, sleep isn't accurate at all (basically everything) I wake up in the mornings and have already walked about 300 steps lol The latch broke off once but it was easy to put back on I didn't return bc i have worn it everyday to keep track of the time, and date
