Oh hell yea. A year ago my dog chewed up my garbage disposal power cord so I stopped using it. Well the drain stopped draining well so I needed to do something about it. Today I went to the store and bought a replacement cord, wired it up and the power kicked in but the blade was stuck. I bought this manual wrench too and the thing wouldn't budge at ALL. I'm horrible doing anything maintenance, home improvement, etc. So I thought I needed s unit replacement and tried to order an installation service call. But their systems were down so I bought the unit and had the weird idea of replacing it myself. When I got home I tried the wrench one last time and it MOVED. So I rewired the disposal again and the drain isn't clogged anymore and I didnt need the replacement unit. So I'm returning that tomorrow and between the new unit and the almost place install request I saved $200.
Accomplishing this home improvement no matter how small is a pretty cool feeling.
