do you have a link or pics.... does it differ from the mainstream media reactor. i would say if the build quality is something you would trust. (ie... putting hands on the product and or seeing it in operation) then go for it.
It's the same as dims of AquaC XL. It's a twist lock type. It built strong to lock it in.
I also have a PM reactors. It's the best reactor than other. These are no nylon bolts to lock it in.
