I wanted a very cheap clip tuner - I bought the Boss one and promptly lost it because I'm useless - and this certainly does the trick. I don't think it's the most accurate tuner on the market, but if you're just a rhythm guitarist like me, and you're lucky enough to have a guitar which is very reliable, this is fine. I really like the screen, which is simple, black and white, and looks kind of retro. You have to get used to which way the screen moves as you tune, but that's normal for all clip tuners. I've only used it so far in well lit rooms but the light of the screen seems pretty strong and I can't imagine that it would be a problem even on dark stages. It is incredibly small and unobtrusive and sits nicely behind the neck. I've used it to tune up my twelve string and it had no problem at all. Definitely worth the price.
