How can I tell if I’m Getting Quality Wall Panels? General problems, solutions, information and advice on fixing to walls of all kinds

[FionaQueen]

I just bought a new apartment last week, and I’m currently planning to set up some wall panels there. One of my friends who lives next door (at the apartment building) told me about this peel and stick wood wall UK provider. I’ve already checked out their site, but the problem is I’m not particularly sure how to check the best panels to get since I haven’t done this before. Any tips? Or advice?
