1. The rubber feet go from relatively easy. They are only plugged, not glued. Without rubber feet Mobi can not stand on flat surfaces.
2. The connecting cable is prone to broken cable on the plug
3. Mobi is not "crash-proof". An unfortunate fall, and the speaker snaps inside of the anchoring. Although still everything works out, pushing together is no longer and with slight movements (also bass!) Rattling the loose speaker in the housing.
Too bad. The sound and the battery life is great. A more robust design would be desirable. So it is not suitable for tough outdoor "pocket use" but only for the well-kept living room.
