Bulb blew once plugged in! Waste of money
Bought this a while back, never used it because the minute I plugged it in the bulb blew out. I just went out and bought an entire new UV sterilizer from my local fish/aquarium store. Was a complete waste of money

As mentioned in other reviews the bulb blew out when first plugging in.Two possibilities here, 1) cheap bulbs2) more likely, there is a light-oil being used for the O-ring seals. This oil gets everywhere on all surfaces of the housing, the crystal housing and the bulb itself. The packaging even had a spot on the cardboard where one of the tube opening was up against it. Instructions for replacing bulb even mention not touching the bulb because of skin oils, use a tissue. Manufacture should take their own advice and maybe package the bulb separate from unit, away from o-ring oil and ask customers to wipe off any oil then carefully install bulb with clean tissue.I did order some replacement bulbs from Amazon and will update my rating after I actually use it. To find bulbs here on amazon I searched for 3Watt UVC Replacement bulb. They are used in pedicure, toothbrush water pick things, if that helps.
