Agreed, I have been using Jebao pumps and wave makers for years without issue. I am currently using 2 of the OW series in my tank. I would get 2 OW-25 for a 75 gallon tank. The beauty of a controllable pump is that you can run it at lower speeds and prolong the life of it.
A lot of people will tell you that Jebao is junk and you will spend more money in the long run to replace them. It is true that they will probably need to be replaced, but IME, it is not true that you will save money by buying Vortec. Just look at how many people have had to replace either a wet side or a dry side on the Vortec pumps. Guess how much they cost... More than replacing Jebao's.
Jebao pumps are great at what they do, and that is to move water.
