Lovely pregnant, very stable and small enough (she holds in one hand) to slip into a bag on a desk beside a PC. Installation is a breeze squarely so it's easy! It works with either a jack or by wifi. Personally I use it almost exclusively in wifi and scope is very satisfactory. I greatly appreciate the ability to recharge (or live feed) directly via USB cable pregnant: it's great. The sound quality is amazing for a speaker of this size (no crachotis, good treble and bass) and I have met the manufacturer's instructions for setting the membrane. In short, after 3 weeks of use, I have nothing but positive feedback. Excellent price / quality ratio. I think buying one for each of my nephews because it is the gift to a teen!
