With any BCC, Your going to find good and bad. I've been using the Protank1 for around 5-6 months now.. Changed more than a couple of wicks in them. Some people have them leak all over. I've never had an issue. Remember these things are cranked out by the hundreds every day, maybe more. I've seen my fair share of poor manufacturing from ALL the Chinese manufacturers. Why should they care about quality. Not their problem. That's why their sold as DOA.
