Tuner works well, charges quickly and lasts a decent length of time, it's easy to read and seems to pick up all of my guitars well (two Squier Strats, a Fender acoustic and a HB SC-450plus) and I actually prefer it to my Snark SN5X.
The plastic, however, feels very cheap, but for the price it's hardly a surprise. The backlight also bleeds through the gaps in the shell, but again, it's not a big deal.
