The band itself is very comfortable to wear, is also broad wrists easily to wear, the plastic feels valuable and the LEDs are very visible. However, what has prompted me to send the Wearable back, is as follows: The functional scope is simply too small, and the reliability can be desired in some cases very left. The connecting mobile phone - band (with a grade 4) was carried out without any problems - then you can adjust 3 Notifications: telephone, alarm and notification. Unfortunately, a chance to try different callers, alarms and notification Apps is not possible to identify with different LED colors. The vibration can be set in 4 different intensities (which differ significantly) the LED brightness in 3 - but I saw little difference. The fitness app showed every time an error that the data can not be synchronized from the band, even though they became a second before synchronized. Partly overthrew the Apps from completely. All in all, the whole (software side) a very immature and unfinished impression. I can imagine that there is still some could come - but I want the product today, not use in one year. And there it is then already new - type device - considerably more powerful. Thus, the question of what you can do with this band all: notifying, when a call comes. Good - but then the phone must be in the vicinity (with the device itself can not make calls). This makes no sense in A., as can one can equal or vibrate the phone to flash. The same is with the alarm or notification. In the latter case you anyway just know that any one of the set Apps has received a notification, so you can then advise whether mail, WhatsApp, threema, Twitter, etc. Who social media is affine here whose wrist vibrates constantly, it should Apps for multiple notification enabled. Another shortcoming is that Razer persistently refuses German instructions enclosed, or to locate the Apps. So who dominated not speak English, were in a fix here. (Certainly in today's world hardly important, but it can certainly make some people with problems. I also think that a product that is sold in Germany, should have at least one German Quick Start Guide.) Finally something positive: The notifications were made all problems. (If the app was not crashed.) Nevertheless: One of the software should still at least half a year to give "mature" - currently it is still too immature..
