easy to assemble (hence the decision against the fixed installation with concrete) and foolproof. It had rained the day before, so the floor was also nice and soft and at the second attempt, the sleeve was screwed perfectly vertical. It costs a bit of strength, but with the included rack there is no problem. The only question that stelt to me: on the description of the clothes dryer Leifheit is that the guarantee only endures when using the supplied (einzubetonierende) ground socket ... because this product is indeed by the company, the warranty should nevertheless endure .... ????? Hopefully I will not be able to enjoy, to have to try it and my clothes dryer last longer than its predecessor (Vileda) ....
