Great value for the price vs. Others I've tried to use!
Tight tolerance, smooth function. Great finish! Impressed by the price for the value-

Works for me
Pretty good for the price. Not as beefy as I thought they'd be, but they'll still work just fine for my project

straight, no binding!
48 inches, straight, no binding. Bearing blocks have smooth motion. Glad i bought 3 sets. No trouble with any of them. 4 stars because i have never rated anything 5 out of 5. These are beefy and worth the price to me.

Good strength and straightness
The blocks could be better cast with better cut threading but overall seem to be pretty straight and strong. Using as guide rails for 10mm thick 410x410 aluminum plate for custom 3d printer. So far with about 20 hours of use on them they have tracked fairly well.
