Review on ToughBuilt TB-S200 Roller Stand/Support Stand: Adjustable Miter Saw Extension, Portable and Foldable for Convenient Storage, Durable Galvanized Steel Roller, Heavy Duty Construction by Badpuppy Warton

I really like my other ToughBuilt products, but they are disappointing for a few reasons: 1) They don't lock in the open position and can collapse unexpectedly, not perfectly centered. This wouldn't be a problem if it wasn't for #2. I added a piece of wood that fits snugly between the legs to avoid this problem. 2) The base slides better than the casters roll. The hard plastic legs slide too easily on my concrete floor. I added some rubberized floor mats to avoid this problem. 3) They must be perfectly aligned or they will have any of the above issues, but the above issues make them easy to move. 4) The height adjustment is finicky and there is no guarantee that the casters will stand straight. Ultimately, I wish I'd paid the extra $7 for omnidirectional reels. This would greatly reduce the impact of some of these issues.
