According to many opinions, dryer on a washing machine needs no special mounting system. However, my tumble dryer (Veudaite) being deeper than my washing machine (bauche), two of his feet were inside the small edge of the "top" of the washing machine, and two were based on it. In short, I thought it was wobbly. As such, the kit has resolved my problem: installed in under 10 minutes with a friend (within muscu make, you have 2 people), the whole is stable and does not need any hole or any technical knowledge; we find an example of mounting tubeyou filmed. The slide tablet well and does not in my case to access the filter at the bottom of the dryer, or laundry hatch at the top of the washing machine. But, only flat, does not seem a rugged durability: I will only small loads (10 kg or less). Finally, a comment on product status: it arrived slightly damaged, I did see the delivery man (think open before him in case) and have photographed - failure did not affect product functionality, simply aesthetics and overall value. The Amazon service, which had assured the shipment to the seller, proved responsive and attentive to my requests, I would recommend you go through a vendor with shipping Amazon.
