Initially had problems where the shopping trolley kept re-directing me to some American "deal of the day" website, that could very easily lose you business. The GU10 LEDs that I ordered are fine, fitted the downlight cage with no problems. I also ordered a dimmer module, unfortunately what was delivered was the wrong item, after a little persuasion the staff checked the item I had ordered vs the item that had been delivered and sent out a correct replacement ... in short mistakes happen and fixing them is what counts, in my case the extra day delay wasn't important.
