Just installed these bad boys under my mini split condenser, and wow—what a difference! The unit used to sound like a distant lawnmower, but now? Barely a hum. The rubber absorbs vibrations like magic.

Installation was straightforward—drilled into concrete, popped in the anchors (which bulge to lock—so satisfying!), and tightened the bolts. The included rubber rings add extra stability. Pro tip: Don’t overtighten or the rubber warps!

Survived an 80mph storm UNBOLTED (oops), thanks to the weight + grip. Only gripe? The nuts rust fast—wish they were stainless. Still, for $20, these are built like car engine mounts. Way better than the flimsy pads that came with my unit.

Smell? Zero issues for me, but one reviewer mentioned a chemical odor. YMMV. For heavy-duty quieting, 10/10 recommend.
