I love mine.
Everything I need in a tiny package. Speed change, pitch change, loop function for tricky bits, tuner, metronome. When the band sends me sketches of songs I use it to record a few different options and send them back for approval. It lives in my bass case and I would buy another if it failed.
I thought the bass sound was crap to start with, but then I replaced my headphones and it was fine.
I do have DAW/interface etc, but for convenience, ease of use, etc, it's great.
