Product review (5 stars): we were pretty familiar with the sound and feel of an earthquake
This has been a complete game changer - saving my a TON of money. I purchased my house almost 2 years ago and it came with an LG TROMM washer and dryer... SCORE! (so I thought). I quickly learned why there was a jack under the floor of the washer upon doing our first load. Being from California, we were pretty familiar with the sound and feel of an earthquake, which is EXACTLY what happened every time our machine hit the spin cycle. I was at the point that I feared we would see structural damage to our house due to the constant shaking from this machine (and that was with half loads on med spin). Laundry was an all day job since I couldn't fill up the machine nor could I spin it very high (thus increasing drying time). And then I found these little feet...

I was skeptical that anything could stop the house from shaking and give me half my day back. But they have!! I can now do a full load of teenagers jeans, spun on high with so much as a rattle in the house. Of course standing directly next to the machine there is a slight vibration but I can live with that. This has been a HUGE game changer!
