sununitec Updated I5 Plus Smartband Sports Activity Tracker 0.91" Horizontal Vertical Exchangeable Touch Screen Smart Bracelet More Than 24 Types Sports Recorder Fitness Tracker Smart Watch

No pride in writing this review, but its my opinion and mine alone, firstly if I want a sports band, i want one that can be read in most circumstance, this one cannot be read in normal daylight as the screen is unreadable due to the light. Secondly any item of this sort should have an app available that marries up with the device, in this case the recommended app does not, for numerous reasons, have taken up the app deficiencies with the app manufacturer but they are not able to help. hence I have returned the Smartband to Amazon with my comments.

Absolutely brilliant, especially for this price. I was looking for an inexpensive smartband that would let me know if there is a text-message or a phone-call and it has been working great. The Zeroner Health app needs to be kept running to maintain the functionality, but it doesn't seem to take much battery.Also, the battery life of it was way better than I expected from a cheap smartband. For me it takes 3-4 weeks before the battery runs out, it is nearly as good as my favourite Kindle Paperwhite.

brilliant product since receiving it I've lost 8 lbs in weight as it makes me move more

Disappointing - data not accurate

The one I have now is a replacement for the first one that came, and didn't function properly. I am pleased with the way this one works, accuracy is pretty good. The seller responded very promptly in sending me a replacement, which I found impressive. I would recommend them as a very good seller. I am only using two sporting functions cycling and the pedometer, both seem to be fairly accurate. Still not sure about the sleep mode, as last night I apparantly walked about half a mile while asleep, but it did record pretty accurately my sleep patterns. Looks the part, so can say I am pretty pleased with this tracker.

I screwed up when I bought this. I`d done so much product searching that my eyeballs were fatigued and I thought it had a heart sensor...it doesnt. MY MISTAKE. However, its a really good piece of kit. The battery lasts an age without charging, almost a week. The app that you download for it (Zeroner Health) works fine and pairs immediately. Only giving it 4 stars cos I screwed up ref the heart monitor but that`s no fault of the product. Well made, looks good. Would definitely recommend.

Works well with my phone to alert me of messages etc and works as a watch, but the pedometer function has about a 30% error so overall not useful. Disappointed.

Sent this back as the buttons were fiddly to enable the different funcation.
