Dropped $200 on a fancy power trowel that sat in my truck for a year before I sold it at a loss
Bought one of those lightweight models thinking it'd save my knees on big floors, but it never could keep up with the heavy stuff and just vibrated my arms numb. Anybody else buy a tool that looked good on paper but just didn't fit the way you actually work?
Hang on, "dance around"? That's a wild way to put it. I've been tiling for over a decade and I thought I'd heard every excuse for a bad finish. But seriously, a lightweight trowel isn't dancing, it's just not doing the work. The whole point is the weight sinks the notches into the thinset, and if you don't have that heft, you're basically just scraping the surface. You're not wrong, I've seen guys try to use those featherlight plastic ones and the thinset just sits there like a puddle.
