I lived in the Eifel, where the power lines still overland and went where with every storm of lightning struck them. Result was that getting any AC adapters subsequently gave up the ghost. Since I in the sockets the Primera surge arrestors this is use never happened. Maybe it was just luck, because each flash is different, but I am inclined to believe that the appropriate parts are any good for her little money. Alone as a preventive measure, it is still worth it today to use these in my opinion, useful surge arrestors.
I have now 9 of these devices, some of them for several years, in use. What I can attest is that none of the connected devices behind is ever broke. OK - all Random ... Security can provide in advance assess bad. Only if damage has occurred, you know what might have been done better.
The housing shape has never bothered me, because I always put a part into the wall socket and then behind a power strip.
