I had it twice, on two different pedal boards.

I tried out many other products: Boss, Arion, Korg and others
I like the reliable display and the latency time. It reacts slowly, which doesn't mean that it doesn't work well, but it doesn't recognize all harmonics which can appear by resonance, and this is a very good thing.
When you're on stage, nothing is more annoying than a tuner which continuously moves: you never know if you are in tune or not!

I would buy it again. I kept one of the two I had because I'm satisfied with it. I sold the second one because I didn't use it anymore.
Today, I would like to try out the TC tuner which seems to be really great. And we all know the quality of TC gear. However, the DT-10 is still a good product.
It's not too big (a bit larger than the Pitchblack or the TC). Mute function, battery or PSU (9 V DC) operation. Easily readable on stage, even with blinding lights.
Also available in rack version, if you have a guitar tech... but I just like the stomp box version.
