I've been reading good reviews of this regulator on different forums out there, anyone here has first-hand experience or heard form anyone using these?

Aquatek CO2 Regulator Solenoid (Single Outlet)

I'm happy with AquaMedic. They are good at being simple and keep a very consistent bubble rate over many days and weeks. But on the flip side: Aquarium Plant's electronic kit is not good that way. Bubble rates vary over a day as much as 33% from moment to moment.
