Expensive, but when used correctly quite well.

I use for several years repeatedly Tesa Power Strips in different versions (Standard, posters, in combination with hook). On the one hand the good pieces are not cheap, but that they actually again without a trace removable.

For bond strength (which has criticized the previous speaker): My experience showed when used correctly - clean, dry, stable base - a very satisfied stellene adhesion. No replacement after a year, quite significant load capacity (ok, not be reviewed in the balance whether the specified load capacity was exact) and no other defects. The only time that I had dropped a hook simply the bond between paint and wood the problem - not between color, Posterstrip and hook ...

I can therefore definitely my speakers do not connect (I suspect because sometimes errors in the application) and also not understand the review!
