I purchased £900 worth of mirror tiles . After placing them on a clean , dry , new wall . So many just fall off . Lots of correspondence with screen with Envy . And all I got was they can’t be responsible for the type of wall I put them on . I placed them on a normal clean dry wall . So I asked them to come and see for themselves . Because what wall would you put them on then as mine was perfect base . Lots of E-mails and basically they wouldn’t send me replacement packs . I did get offered a small refund on one order . But considering I spent £900 that was just rubbish . I am now having to glue each one but by doing that risk ruining the tile . The effect is just lovely . I have so many compliments on them . But so disappointed they are not fit for purpose. And screen with Envy just pushed the blame on me . I am so confident my new walls should of been perfect base . Poor adhesive for the cost they charge .
