Works great with my Iphone

I am very surprised and pleased at how good this watch works. I tried an off brand "smart" watch recently and was let down. This watch works great with an Iphone, I was able to get text messages, facebook messages, and caller I.D. with it. The band is extremely comfortable, snaps on tight, and fits great. I use it at work and was very worried that it would count every move I made with my arm as a step but it didn't, I drove in my delivery van for 45 minutes and the step counter remained the same. It seems quite accurate too, I counted my steps on a few occasions and it was pretty much spot on. I have never had an expensive smart watch, but I would expect the same performance from it as this inexpensive watch.
The time can be set as regular or military time which makes my job easier (we have to use military time), The display also stays off unless you swipe it or just move your wrist, you can choose which. It will tell you how many steps you took, how many miles you walked, and how many calories you burned. I have yet to try the sleep tracker as I charge it at night, but I can only assume that it works just as well as everything else. I received this watch at a discount in exchange for my honest review.

Very comfortable and works well with my iPhone very easy to sync. Only complaint is battery runs out sooner than I would like. But that is just because I talk on phone to much. Also good sound when listening to music or podcasts. I have thought of buying a second one to charge when I am using the other one.

This product works great for my iPhone.  I use my iPhone's Google Maps app as a GPS navigator now, so I don't need to pay for those ridiculously expensive GPS updates for my old GPS device.  I've only used this product attached to my windshield, so I don't know how any of the other accessories work.  But it's a great product, and it looks like it would work with a wide range of smartphones, in addition to the iPhone.

Works great with my iPhone 6, which is in a cover!  I attach it to my JOBY Gorillapod for FaceTime moments with my young grandson.

Works perfect with my iPhone 8 Plus. I have a magnetic case on it so I have it take it off in order to charge it which is the only downfall, but other than that it is great.

This is a great little unit that seems to work very well, sound quality is great and everyone is enjoying it.  My only concern is how the iPhone/iPod docks to the unit and will the connection remain strong over time.  So far so good, and I am thinking of getting one for my work as well.

The plug works great! It charges my iphone while I listen to music.  It also works when it's connected to a wall charger.

I've used this a fair amount (not heavily) since I got it. It paired easily with my iPhone and connects automatically when I unfold it. Works perfectly. The action of the keys are good. Seems to be pretty well built and sturdy.  I'm only writing this review for other people like me who have looked for something like this and have been burned by a few other cheaper options.

Not only works GREAT with my iPhone, but I can copy songs to an SD card, plug it in and I have my own little "ball" or capsule of music. Rechargeable battery makes it the most convenient speaker/player I have seen. I can listen to the speaker, or plug in headphones/headset and listen privately. GREAT BASS too.

This works great with my iPhone 4, I would buy it again if I ever lost it or broke it.

I don't think this will break, though!

Simple, effective.

A quality product!  Works great with my iPhone 8, even with a Otterbox Defender case.  Will probably buy another one for work, so I have one both there and at home.

Works wonderfully with my iPhone 6.  It is well worth the price that I paid.  Fast shipping, and YES, I would buy this again!
