In general everything is fine. Compared to what you paid for, this item is ok. My first one blew out and I think the problem is a cracked inner glass. Raven sent replacements. The second has a small leak on the adapter. I was able to find a way to solve the problem. If I had the money I would buy a better one, but the $70 + 54W UV light is worth a try.
