Review on MTMTOOL 4 Pack Vibration Isolator Absorber by Mike Roe

I have installed a MR COOL UNIVERSAL heat pump on consoles outside. and I had a palpable vibration inside me. When I was about to replace the bracket with a structure. When I started measuring, I saw old rubber pads that were thin as a chip (capacitor heavy. very heavy). ordered from amazon, replaced the rubber feet with these isolators (after buying metric nuts), bam, done, no more noise inside. very satisfied !
