Solidy made and does what it says on the box! I tried it in desperation having tried varios foam pads to stop a portable A/C unit creating resonancies through a suspended floor which could be heard throughout the house and felt through my keyboard. Fitting these to a board which the A/C was paced on eliminated all acoustic coupling to the floor, we are talk=ing about being able to see the A/C vibrating on the platform. No issue with weight of unit (c. 20kg). Makes A/C overall quieter and able to leave on during Teams calls! The vibration levels exceed those I would expect from any domestic speaker.

I am using these with very heavy speakers and they hold up quite well, and allows for a more solid bass.

No doubt there are better isolation products which costs hundreds of £s more than these, however for the improved sound stage, image and clarity these isolation feet did to the sounds I'm very happy to save the money.

Did exactly what I hoped. Was getting bass feedback through my turntable at high volume. Put one of these under each of the three turntable feet and it’s completely solved. It may have tightened bass up at lower volumes too but difficult to say.

There was an indication in the write-up that they were ok for turntable isolatingEven sitting on a flat granite surface there was a tendency for them to lean not sit exactly upright and were thus difficult to positionHad I removed any of the springs which is suggested by the manufacturer that may have be even worse the fact is thatThey resonate a little and the turntable and stylus become unstableHow they would be with a speaker I dont know but can't see the point of using them for speakersI can understand the principleBut they need to be half if not a quarter of the height unless the turntable was the weight of a substantial speaker the best word I can think of is wobble.

Fast delivery always a bonus look good simple design but very effective well built really like this product

We used to get complaints from our downstairs neighbours about the noise coming from our subwoofer for the TV sound bar. Now, we get no complaints and can have the volume at a much louder level than before

Used under fine audio f501 speakers , made speaker slightly wobble like they do with Townsend isolation platforms, sound was smoother slightly more enjoyable..
