Rated 1 out of 5 by Never again Got my neighbour to buy one of these direct when his old cylinder failed. Installed the cylinder and all seemed well until a wet patch appeared under the cylinder, we checked all connections and they were fine so the cylinder had developed a leak, spoke to the manufacturer who despatched a new cylinder on the basis that I would swop it out with the faulty unit and charge them for doing so. Eventually the manufacturer picked up the unit for inspection it then sat around with them for 2 months before they could be bothered to inspect it ( despite both myself and my neighbour chasing) they now say there's nothing wrong with the cylinder and therefore won't pay for changing the unit. As we all know we just pretend that it was leaking for the fun of it They really don't care about the customer and have made no effort whatsoever deal with problem in a prompt manner.

Rated 5 out of 5 by Really Great Product I have been a screwfix customer for a long time, this purchase was my first through screwfix with an outside supplier (non stock item). I received two telephone calls from Screwfix checking that everything had gone smoothly and another from RM Cylinders confirming the purchase and delivery. The item arrived exactly as they said it would. I don't think Screwfix or RM Cylinders did anything on this occasion differently than they normally would do, just a really great product and really great service - Thank You 10 Nov 2014
