I ordered four of these to put under my MFW-15 subwoofer. Very quick shipping, although they are a michigan based company and I'm in michigan
The package arrived today and they had some candy packed in with the feet...haha. Another company with awesome customer service.
As for the product itself, the feet do an excellent job of isolating the sub from the floor. I don't get nearly as many rattles that I was getting in the room. And (as you may have read from my av123 mfw-15 post) maybe my sub was blown before and I just couldn't tell before I put these under it....
