Review on Efficient 8.2ft Unigift Aquarium Water Changer with Airbag and Water Flow Controller by Christine Goldwater

I didn't like it that much. I only bought it because it has a siphon starter and the valve seemed like a nice addition. I ended up throwing away the extremely hard pipe as well as the huge hard pipe siphon. I left the short end with an adjustable valve and pressure trigger. and used my little aqueon siphon on the other end. The result is a nice flexible siphon end that is much smaller. My tanks are quite small and have small gaps between plants/rocks, so the small end of the siphon is much better suited for this. If you do, I recommend going to a hardware store and replacing all of the tubes with something much more flexible.
