Fit perfectly and half of the parts place price. Appear to be well made.

Why did you pick this product vs others?:It's was what I needed

Perfect for my application. Had to replace the gas tank on my RV generator. The tank formed most of the top of the generator but the new tank did not have a recess in the bottom of it for one of the components sticking up from the generator motor. The old tank had rubber grommets in the mounting holes for vibration isolation so I needed some kind of rubber insulator. I had to raise the tank by at least 1inch to clear the motor component. These were just over and inch and fit the bill perfectly. Can't speak for durability but if they come apart anytime soon I will update this review.

Use to mount ac unit ... these are holding up great even though in direct harsh element.

Worked well for isolating a 3/4 HP motor on an old Inca bandsaw. The motor is mounted on the bottom of a wooden table and was acting like a sounding board and this reduced the vibration quite a bit. The mounts are fairly soft rubber so caution is needed when tightening down the bolts.

I purchased these because I had recently installed a wall mounted mini split system outside a bedroom. There was no noise and vibration coming through the wall. After installing these, the noise was reduced by 15 dB inside the bedroom.

Lowered the noise from my hot tub pump by about 5 decibels

They worked as designed
