Very prompt reply re order unfortunately delivery by DPD failed to deliver to address even though there was a person in. DPD delivered to a local drop off point for collection, the so called local post office which not that local!!! Otherwise there would be 5 stars!!! Product great and fitted to cover entry point of Sky cables into building as SKy's product has failed , plastic cracked and fallen off.
