U-Phoria UM2 : I will start saying that my review is so good, because I considered price and my usage

Indeed, I wanted something lightweight, straight forward that connect seemingly to my iPad and that I can put into any gig bag pocket. Also inexpensive since I will only use it for that purpose. At my home studio I have all pieces of gear I need. So this is for the moves. The built quality is okay and even good if we consider the price. It looks cool and it is very easy to use. Do not expect a professional full featured 192 KHz, great headroom, metal cased interface for this price :-) This is not intended for that and therefore it is far from that. But, if you need a noiseless 48 KHz, right sounding, lightweight, just ok headroom, inexpensive sound interface for mobile usage, just go for it. You will not regret. Just €33!
