"The panels are accurately made to size and have no obvious manufacturing defects; the delivery service is reliable and useful. However they are not a high grade product. They are fairly flimsily made and far less strong than comparable panels I have bought from a local building firm. Having said that, I will be keeping the receipt carefully since the things are guaranteed against rot for 10 years - a useful reassurance. But I do wish they were stronger, for when the next hurricane comes."
