Ansich the device for that price would not be bad, if not of all the control buttons (track skip, etc.) would be constructed so cheap. As a key after only 3 months "stuck" or had no more pressure point, I screwed open the device yourself, as we (when the unit is weeks to repair, and then, if necessary, rejected warranty) wanted to spare us the drama of our son. Here I discovered, these are the keys of the cheapest plastic and are also "maintained" by jeweis two 1-2mm thin Platikstäbchen. I was able to discover, were the holding chopsticks partly dawned with the other keys, and here also, sooner or later threatened the total failure. That sooner or later break down (this requires no great act of violence), is probably the dumbest builder clear. The unit has been treated neither coarse nor is it dropped. In this respect, even the moderate price of this small life is a waste of money!
Had taken a slightly higher cost of materials, at least for the control keys in the purchase and made the unit a few euros more expensive, the rating would have been much better.
