Product review (1 stars): Meh, returned - product missing key pieces from photo. Just built my own.
Returned this, as it did not come with the rubber strips shown in the product photo. Plus, I just took the time to build my own wood base platform to secure the dryer on top of the washer, then wrapped the entire package with a heavy duty ratchet strap. These units do not move around at all now.

Wasn't really convinced about how secure the units would be from just two small brackets of metal attached to the back anyways.
