Erector Review: “The Bazooka Bob just gets (bleep) done” -Izzy, CA

Sorry Izzy, we had to”bleep” that….. It’s a family show, but thanks for the kind words




Erector review– “I used a laser once that turned out to be off. Cost me 3 days recutting holes.”  That just never happens with a Bazooka Bob.
