So far so good. Decided to update the entire house to LED to save on Electricity bills. They are hundreds of companies now selling LED bulbs so was hard to choose a particular company. I picked you as you appear to provide all the necessary LED bulb combinations that I required and the website was clean, uncluttered and easy to use. Prices were average given there are a lot out there offering what appear to be similar products significantly less price. Anyway I am now about 50% of the way there and all bulbs purchased thus far arrived speedily and are working brilliantly. Free delivery on purchases over £40 is great!. Website is well structured and ordering is easy. Only time will tell if bulbs last as long as stated! Rest assured I will be returning any that fail within the 5 year warranty period. The 5 year warranty was also a factor is my decision to use MirrorStone as Like the rest if us I am sick and tied of buying bulbs that last a few months only when they are supposed to last thousands of hours! So far all bulbs have fitted perfectly. These include GU10, MR16, E14, G9, MR11, E14, E27 and B22. The E27 R63, B22's and E14's are especially good giving a great light spread and are in fact better than the old Halogen bulbs they replaced. I am now looking at replacing all the MR16 dimmable bulbs and dimmer switches of which I have 30.
