I bought vinyl click , 24m2 . I am a joiner with 30 years experience and now a site manager so i know what I'm talking about. The end joints only sit into each other and click when you walk on them . I installed the flooring with a thin acoustic underlay and treated it with as much finesse as i could, as i know how brittle it can be. Honestly the worst quality of flooring I've ever installed and it was £20 a square meter so not cheap. I really regret buying this. Delivery date was changed twice from original date chosen and i was only notified when i called the company.. Poor quality and poor service, Spent nearly £500 and NOT HAPPY
