Actually, a huge disappointment. I've been so looking forward to the Activity belt. Even wanted soon a second order for my son. When the band arrived, unpacked and then ... already got the first disillusionment. There is no charge to the pad or stand where you can recharge the thing (with the cheap electric toothbrushes standard), but a small part / plug that has to be (!) With a rubber band on the device strap! , Well, I have loudly scolded and strapped the thing. A further step, the strip is supposed to work with the smartphone together. I have the Samsung Galaxy S4 Active, ie an actual cell phone and not Nokia 3310. In the Google Play store I checked before ordering, and even found two apps to control the functions. Then came the shock! Downloaded app, no connection to the tape, nothing !. Tried the other app, nothing! In the user guide the ribbon looked ... because a completely different app is called as necessary. After a long search (direct entry in the Play Store did not produce a result) has been found, the app is not compatible with my phone. So I can not use the tape? Can not be! I have written to the app developer and the company TIMEX, have described my problem and asked to answer. No Reaction! I think it's not impossible to check or adjust the app? Not all people have a particular smartphone model and the activity band is supposed to work with as many mobile phones. If the company TIMEX but is so conceited and arrogant not even write a short answer, they can retain their lump scrap or throw it to the incompetent developers. I need something not, any more than I will therefore buy a new smartphone. Anything else. The Internet page of TIMEX is Eiin class example how to make a possible opaque, unhelpful and completely content blank page for me. No matter where you click, you do not get concrete information. Just beautiful (so beautiful they are not) photos. So you probably tried to deceive the desperate users. TIMEX BYE !!!!
