Product review (5 stars): Appliance salespeople are idiots!
If you are an appliance salesperson and do not offer these you need to have your head examined.

We've had our Bosch laundry pair for a few years now and it's been a love-hate relationship.  I'm not the one who does the laundry, but I'm the one who hears them run and gets sent running to "catch the washer" before it gets up against the wall or falls off of the platform.  You see the high rpm (1100) spin speed that gets the clothes so dry also can create a lot of vibration depending on the load size.  When we built our new home we decided that a first floor laundry was a must.  I designed the cabinet base and tops so that they are 15" off the floor for an easy load height.  I spec's a center cabinet  to separate the machines.  I spec'd a pair of 15" high base cabinets with a single drawer and topped them with the same granite as the countertops in our kitchen to add some mass and hopefully deaden vibration.  This works quite well for the most part, but the washer is constantly walking whenever it spins out.  Once it even came forward enough to drop off the front of the slab top.  We added bumpers between the cabinet and the wall which did help, but not really enough and when it got up against them it got really loud.  We bought the same laundry pair for my Mother at the same time and her washer walked all around the bare concrete basement floor also.

So I started searching and came across silent feet.  I'll be honest, on first impression and with the limited presence and relatively high price they seemed like something you'd see on an infomercial or something.  They kind of gave the impression of one of those miracle products that are overpriced junk.  Part of what got my attention was the mention of sorbothane.  I rememeber this from an early 1980's TV show called "That's Incredible" and was surprised to find the episode on you tube.  (...)

I decided based on reviews here on Amazon etc. to give this product a try.  I started to search locally to see if anyone had them and quickly realized that I was wasting my time.  I ordered from Amazon and they showed up on the 24th which is much quicker than the estimated date of 12-28. I just installed them yesterday 12-26.  Unpackaging them and finding them sticking to the packaging inspired immediate confidence.  Today we put them to the test.  Once in operation the difference was immediately obvious.  I was initially concerned because I didn't get the granite as clean as I had hoped for under the rear feet, but at this point it appears as though they are stuck down nice and tight.  While I realize this is a very short term review based on initial impressions, I'm quite confident that these are the real deal and will do what we need them to.

I should also add the Bosch makes a hold down "bracket" set to keep their machines from walking, but it requires it be screwed down to the platform which I find ridiculous.  I mean who is going to put a hole in their floor to anchor an appliance?
