Good quality but don't plan on using them with 85 lb per caster. Used them for my planters. Swivel on them work and for a rolling light pedestal that i made.

I'm a novice diy'er and bought these little wheels with brakes - oh my gosh they're awesome. Smooth rotation allows for effortless maneuverability.

The twelve i bought are defective all of them. Most of them are bent and coated with this black, thick lard type of grease. The locks are super hard to engage and the wheels don't rotate or swivel easily.
