When ordering Acoustic Tiles from eFoam I wanted a small sample but had to pay for this even though my eventual order was over £300. When order arrived it was short by one acoustic tile but luckily as the tiles came in 'packs' I had over compensated and had enough. The 'super strength' spray glue does not cover the square metre coverage as specified on the rear of the tin so I ran out of glue 3/4 way through, and be warned this glue is not as industrial strength as stated on the eFoam website and although my acoustic tiles are still in place some are a little loose. Delivery was spot on, very quick. Good products and service from eFoam just be aware of some minor hitches that may occur.
