Initially had some problems, then read the manual. Taken on holiday to play some music when sitting outside our mobile home. Worked very well and loud enough for the job whilst obviously not being at disco levels. Worth noting that although you can skip tracks it is better to have a selction on micro SD cards to suit the occassion.
Bought this item to store DVD's from my collection to view on a media plyer when on holiday. Loaded and played back without any problems unlike some usb sticks i had tried previously thinking they would be more resilient.
Bought to replace a blue one which looked a little too like the other plastic knives in the picnic basket for comfort. Very sharp, works well and the cover is essential when you are diving into the depths of a bag in the dark1
