Pro-Lift Mechanic 2 in 1 Foldable Creeper Seat

fell apart after 3 months of intermittent use. I use this to do occasional maintenance on my vehicles, I have maybe used it 10xs and 3 of the 6 wheels are belt or wobbling loose. I weigh only 170lbs at 6ft tall, there is no way this could hold up to 300lbs. Good luck trying to track down the warranty details, they seem to be non-existent.
