getting smaller and smaller

I was looking for an MP3 player for my 3 year old daughter, so that she can hear her children's songs in the room. To date, a small CD player in action, but was abused by her had übelst (deck, CD out, etc.) The CDs were all getting scratched and unplayable. It's frustrating. Why give it as MP3 - a player had to be in the lower price range.
Today, the part arrived. The package was the size of a garment-mail order package (approx A3 and 10 cm high) and also rel. "difficult". After unpacking was soon clear - the package from the MP3 player is much smaller and most of the weight came from the enclosed magazine :-) After the direct product packaging was removed, a small cube wunzig appeared. Cute! I thought - looking out very kaputtbar. But none. The thing feels surprisingly high and the handling is very easy. The Micro-SD card can be sunk almost entirely in the slot, so nothing protrudes.
The most pleasant surprise came but when tested - the sound is really excellent for this mini-sub! Battery life I'll try later, but I did anyway rather matter when buying. Am already thinking to get me another 1-2 such parts for garden and terrace. I'm totally thrilled!
