I bought this because both washing machine and dryer in the laundry room now should stand above the other. Through a very high momentum of the machine, it was too risky to put the two devices only so aufeinader. We have to stabilize the frame (ie under the dryer) attached two felt strips, so that the machine is clean. The feet we agreed, so that the machine is resting evenly on 4 points. This allows the board also pull well. The supplied strap is perfect and keeps everything well together.
