Yep I have two of them, IMO they are the best value for money pump. Do be aware that they are no longer green and have threaded connections on them. I now have a green one and the newer grey one. They are both very quiet but the green one is quieter. I have had the green one for a couple of years with no problems at all.
Were barbed , now threaded. The barbed one works well because i have it running straight to silicon tube. The threaded one works well and looks pretty with the stainless barbed connection.
I've got two kaixin also and no complaints. The only trouble I had was one of the plastic threads was a bit hard to start but by holding my tongue to the right it went on.
