Currently putting the pieces together for a 40b. Just ordered 2 Jebao slw-20’s. Anyone have and experience with these

I have them. They are nice. Typically I prefer a less open back to wavemakers but I haven't ran into any issues (there are home made anemone guards people sell for them if you are worried)
