I placed them on a stand I made for my DW735 thicknesser (about 100 pounds). I don't use a planer that often, but when I do I usually cut a lot of material and want to avoid traditional rollers as they tend to wobble as the material is fed. They are good in the side position. but with them, even the tiniest shavings on my slick concrete floor can wreck a wheel. The geometry just doesn't feel right as the misalignment of the reel puts the lever in a very dangerous situation as the reel spins towards the stand. I'll have to check out Rockler and see if they're different (they're twice the price) because I might have got what I paid for. Wouldn't buy again.
