Review on Penn Plax Bendable Bubble-Wall BWB2 Air Diffusers for Enhanced Aquarium Aeration by Christina Martin

Fits perfectly in my AeroGarden Bounty Basic. 60cm is enough to go around the tank for full root coverage. It holds the shape I bent very well and doesn't float. I use a small, stingray-shaped Mylivell air pump so bubbles don't come out of every hole, but they bubble up pretty evenly along the hose. The bubbles are much quieter than the tiny air stone that came with my air pump. He was there for several weeks and had no problems. My roots look nice and healthy so I'm very happy with it. I'll update if the algae clog it up or something.
