The unit works fine but the bypass on/off button is a little bit stubborn, I had to stretch out the internal spring underneath the foot switch to make it work better. You may have to do the same after a while, just pop open the foot switch by pressing the two buttons on the side, take out the black plastic part with the spring on it, and stretch out the spring and put it back together. In order to turn the bypass on off button, make sure you press hard till you hear a click.

While there is no problem with operation currently, I can't guarantee future reliability of this unit, since online reviews commonly mention the bypass on/off and tap tempo switch failing. Hence this unit is being sold as is and returns are not accepted. Ships with what's shown, no box and no power supply.
