Mine lasted like.. 9 months? And it broke from a 1-foot fall onto a carpeted floor. The plastic holding the footswitch on broke, meaning it flops all over the place. the switch doesn't work correctly anymore either because of it. and the thing never worked right anyway, half the time you'd have to turn it off and back on a few times to get it working, and it makes noises sometimes when your amp is up loud, not very good in a live setting..
basically, don't buy these, they're crap, spend the extra 20 dollars on the boss which will last 20 years
