After a lengthy selection I decided against a cheaper alternative for 30 EUR and for the significantly high sounding product of Störch. Shipping and product are properly! I obviously can not speak for others, but my product is extremely solid and installed without error (exactly as originally expected from the photos). With me nothing and bend wobbles can already erstrecht nothing. If you have an arm possibly not 100% mounted vertically, can also all reference to several settings still readjust (Warning: These screws must be tightened in any case when assembling something, because otherwise the television just is not stuck and wobbles as have some already described). The assembly worked perfectly for me. There is a well-to-understand instructions and there are also different screw sizes for mounting included (you do not need any additional mounting parts, possibly even die because of the supplied wrench course is rather an emergency solution, if one at home does not have a toolbox). I had also no problems with the supplied dowels and although the walls old building (indeed solid, but it is classic old building). By rotating anchor is a known issue when you drill the hole too large or the hole deflects during drilling. If you have bad walls, it usually helps when choosing smaller the bit number. For me, the 10 was however perfectly. So, what can I say ... for me the thing holds definitely bombproof and works flawlessly! Therefore, 5 stars!
