Piece of junk. Not sure this is true with all 298AT, but this one is useless. It will not lock on, or off the coupler. I elected to return it for a refund.

It isn't working. I've contacted the manufacture, and they tell me they will still cover it under warranty if I ship it to them. Hopefully a replacement will do the job. I'll wait and see.

I must have got a bad one. This thing has many good reviews, yet mine simply does not work at all. It did once or twice. It lights up but its like it thinks while the guitar is ringing, then it displays nothing. I changed battery but there was no change. I need a reliable tuner. This  didn't work for me.
