I loved this tuner - the clip itself is probably the sturdiest and most well built of any clip-on tuner I've tried. The display is super bright and colorful, and just plain looks cool - it almost likes a display on an old handheld video game, but event crisper. It's pretty accurate too. It's somewhat large, however, and if you have a small headstock, you might find it hard to make it fit. The plastic is made of has this really cool rubberized matte feel to it, which is quite nice.
Problem is, while the clip is sturdy, the neck (what attaches the display to the clip) is not. The neck is held in place by a 3 pronged plastic rotating joint - problem is, those prongs are very easy to break. The neck too, is easy to break. I've had 2 of these, and with one, the neck broke off (while in a padded, protected pocket too!), and with the other, one of the prongs broke off (while attached to my guitar). Chances are, if you're like me, you'll want to keep this on your guitar all the time - if you do, I all but guarantee it will one day snap on you. Shame, because it's really nice otherwise.
