The Kamoers are pretty decent pumps, so I would likely go with one of those. I personally will never put another Jebao cheap knock off on my tanks, especially for something that can have the potential to crash the tank. I know their price point is very attractive but a dosing pump is one of those items that can easily crash a tank, especially smaller tanks, so I would go with something that is going to be more reliable and has better precision. This is certainly one of those items that you get what you pay for
