I have the iTrack Solo. It isn't bad but I would say that if you are just recording so that you can identify what to work on better you don't need it, whereas if you are trying to make a quality recording then you are going to want two mics, and the Solo limits you to one. It's also a bit clunky in some ways. You need external power, there is no on/off switch on the unit itself, and (assuming you're using it with an iPad rather than a PC or Mac) you have to hook it up to an external speaker even if you just want a quick listen. You can't play what you have recorded through the iPad's internal speakers unless you disconnect the unit, which is a pain and will eventually damage the socket, if my experience with my last Android phone is anything to go by.
