Thought this would be useful, instead of 'up/down' pumping to make a siphon (which is a bit of a pain in an under-tank sump) I could just squeeze the ball. Unfortunately the seals around the squeeze ball are quite poor. I had a hard time generating enough suction to start the siphon and generally got water all over the place. Now I'm back to a simple siphon and this one is in the landfill. (Posted on 1/3/12)

does what it says it will do.. hose could be a bit softer though.. (Posted on 11/29/11)

The instant siphon works however the hose is way to small. It doesn't siphon fast enough for me. It is an ok unit (Posted on 11/19/11)

Ball leaked pretty quickly. The stiff hose makes it difficult to work with. Using the little valve is two man op. Can't hold tube, outlet line and turn valve. One of the few below avg products from BRS. (Posted on 11/8/11)

I was excited to see this item on clearance, as I had been looking for something like this to clean my tank with. It does what it's made to do. However I wish the hose was made from softer material. It comes coiled like in the picture, so the hose is semi-permanently coiled. This makes it a bit challenging to hold the end down into a bucket, because it keeps wanting to recoil back upwards. It also makes the intake end difficult to hold straight down to reach the areas you want to siphon (same problem). I could probably leave it out in the sun to heat it up and soften it.
