Easy to order. Competitively priced though prices are increasing sharply (all prices, to be fair). Arrives promptly. Well packaged to minimize possibility of damage in shipment. Packaging makes secure storage easy if extras are ordered (keeping a spare is a good idea). An important question I can't yet answer is lifetime (still less than one month on first set in dual UV sterilizer). Disappointed that bulb holder is not also sold but available elsewhere. Will order bulb(s) again at this outlet if lifetime is satisfactory. 4-star rather than 5-star only because the lifetime question isn't answered yet; otherwise, I would have given 5-stars.
