Solid product
These work, but make sure you understand the measurements before you purchase. For subwoofers on carpet these would not have an effect. I used them to stack two identical subs on top of each other and they are great for that. Also, they could be used for components lacking feet. The challenge is that they do not come with adhesive. If you plan on keeping the item placed on this in the same spot for a long time and can drop it on top, no big deal, but if you want to slide a large component on top of these, it is basically impossible as they don't have adhesive. They are solidly built just know what you are getting and the size.

Fantastic Isolation Feet
I'm using these with a pair of Kef R2 Metas turned vertically which makes them tall/narrow and need a solid set of isolation pads to prevent sway and of course vibration into the console table they rest on. The isolation feet are dense to the touch and can support 37.5 lbs per pad which I can confidently say is the case. They have an excellent sticky factor so if you try and slide or move them, there's great resistance. There are zero vibrations coming form the console the speakers sit on, and while the speakers I have don't push a ton of air, it's enough at higher volume they can vibrate at high intensity and these pads completly eliminate unwanted noise. Buy them with confidence, they are fantastic and well worth the investment.

Saved my $500 soundbar from the junk pile.
It actually stopped transmitting the boom of my subwoofer to the townhouse next door. We were at the point of junking the sound bar and subwoofer because of the booming noise that my townhouse neighbor was getting, or finding a solution. And these silicone isolation bars did it. Couldn't believe it. But they worked. I thank the manufacturer and so does my neighbor. Saved my $500 soundbar from the junk pile.

They Are Really Expensive
Even though they are really expensive, I thought I would give them a try as I needed support (feet) for a platform. They support that platform perfectly, and the amp goes on top of that. The look is great, but for the price? I cannot tell about improved, perhaps - but, did I mention they are really expensive? So, five stars for the look, but not more than that. Also, did I mention that they are really .......

Seem legit to me..
I have a budget hifi system. For those of you guys who are aren't familiar with hifi/audiophile systems...budget still means quite a few dimes. I cant say about improvement because it worked out to where I'm setting everything up at once. I needed to separate my intergrated and power amplifier that I have stacked and to put something between the amplifier and shelf. Bought 4 sets. Using the other two for my turntable and cutting board. Figure since I have a pair of down firing subs...i should have something there for my gear. People have mentioned Herbies and wither or not these are knockoffs... I have no idea... but these seem to be doing their job and are apparently made with the same material as Herbies. Unless there's a secret to making things out of silicone then I dont see why these can't be legit for half the cost. Time will tell...but I have yet to notice vibrations distorting my sound using these. Guess if you have the money for Herbies...go for it..I mean why not. But I'm using the money saved for another power cord :p

produit simple, qui semble qualitatif, attention à l'usage
le produit recu est simple et semble de bonne qualité, pas trop rigide, pas trop mou. cependant, mon but était de poser sous des colonne d'1m50 hauteur de 20 kg. C'est cuit, le centre de gravité est trop haut, ca bouge. Pas de moyen de fixer sauf adhésif double face. Donc attention à l'usage, sous un ampli ou equivalent, sous des enceintes de petites tailles OK, mais sur des produits trop haut, pas la peine. Bref je suis un peu déçu, j'en ai pris 8 et il va falloir que je détourne l'usage sous lecteur CD ou ampli ou éventuellement petites enceintes. Dans le sachet il y a 8 éléments : 4 firm blocks and 4 rondelles de 3 /4 mm de hauteur. Même matière.

Used for Subwoofer - Small Item - Very significant improvement in Sound quality
Used these to isolate my subwoofer (Yamaha SW320) from the floor. Improved and tighter low frequencies. The overall sound stage is much cleaner now. I am using KRK Rokit 5 Gen4 monitor speakers with the Yamaha subwoofer.

Good but should come with adhesive squares
Despite this, they are the right size for many applications. Quite sturdy.

Surprisingly effective
Used these underneath my turntable and amplifier. Immediately noticed a tighter base, better timing and a more pleasant sounding system. For the price I definitely recommend this easy fix.

Semplicemente perfetti
Ho acquistato il modello squadrato nella versione più dura perchè ho un piccolo impianto disposto a torre e li avrei messi sotto a tutto. L'effetto che volevo ottenere inoltre era di completa invisibilità di questi supporti e devo dire che sono alti il giusto per tenere sollevato l'apparato quel tanto che basta perchè i suoi piedini non tocchino. Oltre a questo ho avuto pieno supporto da parte della ditta per qualche mio dubbio sul modello più adatto alle mie esigenze e sul modo migliore per usarli. I supporti squadrati non hanno adesivo quindi ho usato con successo un po' di blue tack, questo mi ha permesso anche di fare una livellatura di fino sfruttando la morbidezza e lo spessore del blue tack. A livello sonoro ho notato sul lettore CD un miglioramento dei bassi e della definizione generale, segno che il loro lavoro di smorzamento vibrazioni lo sanno fare.
