Howdy,
I got a replacement for one of my backup B 11 silent air pumps which I've had for close to 20 years. Not sure when Penn-Plax changed the design, but compare the two. They used to nicely contain everything, but the one I got today is totally stripped down with everything exposed and loose wires, what a disappointment. Really a shoddy piece of aquarium equipment now.
Dang, they don't make them the way they used to. Even the case is flimsy, but incredibly hard to open.
