Query: Wow!

Remodeling a 70's family home. We're actually rescuing it. It came back into the family recently and coincided with our retirement and my wife and I decided to turn it into our last home.This simple but ingenious tool allows me to do three times what I could do without it. I'm 62 years old and can't grab and carry like I could a couple of decades ago.I want to know who invented it so I can send them a whopper thank you.Easy to load and roll.Set the Troll against the panel, tilt the panel a little away from the Troll, lift and place into Troll in the middle then roll it to wherever you want. Dismount is just as simple. You're only lifting one end a few inches.When you encounter something the Troll's wheels can't cross ... move to center, grab the handle and with a simple ergonomic lift straight up ... you're rolling again.One of those "I wish I had thought of it" gizmos.Wow!
