Review on 🦾 6T Heavy Duty Machine Dolly Skate: Efficient Roller Mover for Cargo Trolleys - 13200 lbs Capacity with Non-Slip Belt by Susan Park

I bought 4 of these to move a 1000lb commercial double stack oven. I put 1 in each corner. They only move in a straight line, so if you try to turn, they'll slip out. Every time I tried to adjust one, I had to adjust all 4. The wheels spin well and hold the weight with no problems, but they just don't work as shown in the picture. I can't go back because I threw away the boxes. What good is a handcart if the wheels only move in one direction. I suppose if you want to move a device back and forth in a straight line, they're fine. Otherwise don't waste your money.
