Positive features:
- Well processed
- (Press audible "click" when) keys very easy to use
- Speech (Power On / Off Pairing)
- Splash-proof (can therefore be easily used in the bathroom or outside the backpack and holding a little rain stand, a small carabiner can be seen in the photos attached for it)
- Rubber suction cup on the back keeps very well (held even after a few days in a stainless steel cabinet yet to be!)
Negative characteristics:
- Sound is OK, but in this size I've heard much better (possibly here was a compromise to close a result of water resistance ...)
- Manual only in English but easy to understand
Conclusion:
For the low price a good companion if it can also be wet.
