This pedal offers many options to make looping an art form. There's sinc and serial modes, fade, tape stop, half time and double time, the dip switches on the back allow you to costumize some funtions according to your needs (Tone print editor would be perfect!). All stuff you don't get in most loopers on this price range.
I've had many loopers - all the BOSS, Akai Headrush, Line 6 DL4, and this one is the best for my needs. Not too limited, not too big, and not too expensive.
It stoped working after 2 years. I wrote to TC eletronic and they told me to send it back and it came back working as new. I got another one just in case...
What I don't like:
a) Fade mode fades too quickly
b) Tape Stop mode also stops too quickly
c) Play Once mode is quite useless because there's a Stop switch. It would be usefull if it was a start-stop switch for the selected loop, so it would be something like the stop switch on a DL4.
d) Stop switch should stop all and start all (again, like the DL4).
