5 Stars – Perfect for Walkers!
I absolutely love this fitness tracker! As someone who loves to walk, this watch has been a game-changer. It’s small, sleek, and doesn’t feel bulky on my wrist, which is a big plus for me. It’s easy to use, the accuracy is perfect as well. It tracks all my activities accurately, and I’m especially impressed with the continuous heart rate monitoring. I can see how my heart rate changes during my walks, which is super useful.The sleep monitor is also really helpful. It gives me a detailed breakdown of my sleep quality, which I never thought I needed until I had it. The blood oxygen monitor is another cool feature, especially when I’m pushing myself during exercise.The IP68 waterproof rating is a nice bonus, as I don’t have to worry about getting it wet when it’s raining or while I’m washing my hands. It’s a solid and reliable tracker that helps me stay on top of my health without feeling like I’m wearing a bulky device. Highly recommend it to anyone who loves walking or just wants a simple, effective fitness tracker! Overall great value for the money!

A simple tracker with many useful extras. Great value option.
This is the second one I bought. The first I got as a gift for my dad who has heart issues and needs to monitor regularly. This is perfect for him. I also need a good sleep monitor and so far it’s had all the info I need. Shipped incredibly fast and comes with charger and two band choices.

Nice quality and size but can’t answer calls on it
Nice quality. Held a good charge. Doesn’t accept calls…I should have read it closer.

Works on iPhone but not Nike Apps
I bought two pairs of this Fitness Tracker for my sons to track their miles per day for a fitness competition.The Good:Device accurately works for iPhone tracking purpose and was a great value for the money.The Bad:The device would not work with the NIKE fitness app that everyone was using to for the fitness competition. So although the device works for everyday use, it did not work for the reason we purchase it. So it was a wasted investment.

No chance Don’t buy
No chance it’s tracking anything correctly. Don’t waste your $it’s comfortable & setup didn’t take long but those points are moot because it doesn’t track correctly at all

Great Watch!
I really like this smart watch! It’s modern and stylish, so I can wear it to work but also work out with it. It’s easy to use and intuitive with simple and modern display. I wore it on a run today and it did a great job measuring my heart rate as well as my run time and distance. It’s syncs well with my iPhone and it has fresh battery life! I’d definitely recommend this!

Works great, synced up fast and fits any 18mm watch bands
This watch is a great option for those who don’t want the big price, expensive type of fitness watches. Under $40 at time of purchase, it comes with a spare band and had an 18mm band size that will fit well with any 18 mm bands. I have smaller sized wrists and the silicone bands worked well, although had a problem getting a perfectly comfortable slot on the band, so I did end up getting 18mm watch bands to fit this and have more comfortable wear. The watch is wearable when doing dishes or showering, doesn’t have any issues whatsoever. I don’t know how long the screen will last, the production company has no screen covers, but the customer service team is phenomenal at getting things set up for replacements if there’s anything broken, plus when setting up their warranty, you get an extra charging cable sent to you. I have an android phone, moto g 2022 and it paired well with the watch through the accompanied app. Sometimes there are some syncing issues like with the weather, but I’ve been able to get them fixed without doing anything crazy. The training options in the app are a bit confusing, and although I do sometimes more than double my goal on steps, I don’t see my training goals filled sometimes. That being said, this watch works great, and although I haven’t tried any of the texting capabilities, I have used it to pause and play my music. It does track my steps pretty well, from myself watching the steps count as I took the steps and witnessed it count the accurate amount aside from one or two that it may have over or under counted. Definitely recommend using the app, it makes the watch a million times more customizable with features as well as the watch face itself.
