I bought this for my husband as he is wary of clip on phone cases. However it was fine until he forgot he had it and then caught it whilst sitting down and broke the clip. However, until that point my husband was very impressed.
Really liked this little gadget... has a good sound and if you have more than one (like I do) you can plug them into each other... more sound! You charge via the computer or an USB charger plug and it is quite fast (couple of hours at most). Recommend it.
