Feature:
It offers a lot in a small package.

Quality:
It's got to take some lumps on this category. I'm sure it will hold up on a board, but it won't outlast a Boss pedal.

Value:
For the money, you won't find anything with this many effects rolled into one.

Desirability:
I use a bit of pitch shift, chorus, trem, etc... Not enough to warrant top-dollar boutique pedals for those effects. This suits my needs well. I have a Zoom G1 on the way. It's a bit bigger, so if it doesn't wow me compared to the sounds I'm getting out of this I wil lkeep the Behringer on my pedalboard.

Sound:
Jack of all trades, master of none.

Ease of Use:
Pretty easy to use, but since the parameter controls aren't marked for instant dialing it takes a bit longer.

Overall:
Great value, recommended if you just dabble in these effects, but want something to call on once in a while. The bypass is actually pretty good. No discernable tone-suckage with it.
