Why should you pay for something that you can do for yourself? Or so is the motto of Sweden. Why should we deliver the product ready assembled, if you can make the make the customers and optimize profits? So it should actually be called, and the manufacturer of this part clearly understood. Approximately one third of the time required for assembly time comes for it, a maximum peel the protective film from the stainless steel sheets in bill size, at the edges correspondingly smaller. A stronger a few μ film would probably detract from the profit not particularly, but spare the buyer a lot of frustration. Another third is required also as an accomplished handyman, see the assembly instructions no contrast, from an unfavorable angle shown and extremely poor in detail what actually from a wish ([...]). In particular, the installation of thermal insulation sheet requires a little imagination. The numbering of the screws and the continuous sheets related is the coronation; a simple image - perhaps in 1: 1 scale - would make no more effort even more pages required, which can IKEA much better! Most screw are only weakly magnetic, but unfortunately not all. In addition to thin and thus cheap to protective film can be here again well and like to save 5 cents by not all stainless steel screws used - a little embarrassing, given the price range. But those who have fought through adversity and given the low screws into scrap metal, will be rewarded with a heater, the - as expected - to work to the full satisfaction and in the design is different from the cheap parts from the hardware store at least. So buy recommendation for those who do not be intimidated by the assembly instructions!
