good product, at inflated prices

The instructions of AEG appliances is extremely poor, with regard to the selection of accessories. The website is nothing here, except the name of the product.
The SKP11 seems to be the STA9 to instructions. If that's so, right here in the small picture of the search list and price list, but not in the product information. 100% sure I'm not.
The SKP11, STA9 and STA8 only suitable when dryer and washing machine AEG / Electrolux and Co. are. They fit the design of the case and would be on the other washing machines, at least not optimal.
The SKP11 / STA9 always fit and has an additional pull-out plate. Due to the metal rails, as they are also used in furniture, I do not trust the bear also a full laundry basket. That is practical.
The STA8 has no extensible top! The photo is wrong here.
How to determine the right one, therefore assesses the size of the machine, I learned only from the instructions of the sets. Take that measure from the front where it is straight (not above, not below, not the door) and measure from there to the rearmost positions (possibly the cover plate). If the machine here deeper than 56cm, the STA8 not fit.
The BR11 consists of screws and suction cups. This is the cheapest option and the price, which then also can hold on a non-AEG AEG washing machine a dryer. How good is, I can not say. After the consideration of the three items I chose for the SKP11.
Unfortunately, I must write to me here unusual times: Unlike this great market place with many retailers in the pictures redcoon prices are accurate and realistic. And just where I get all three in order to compare them.
