These work well and are inexpensive. I use two , one to transfer fuels to my generators and other power equipment and one to drain the oil from my turkey fryer. I tryed the battery powered pumps on the fryer oil, and found that if you did not remove every little drop of oil from the pump before storing they would soon freeze up . These don't have that problem 5 stars

The only reason this product doesn't have 5 stars, is the curve it has because it comes rolled in one box.
If the siphon is straight from the beggining, there would be no mess in doing the first siphoning; as the hose doesn't reach the bottom of the fuel recipients because of the curves. 4 stars

This does exactly what it's supposed to do.
I use it to fuel small watercraft and this has made the job easy and spill free.
I can't believe something this simple that works so well wasn't invented years ago. 5 stars

The Super Siphon takes a bit of repetitive jiggling of the ball end to get the siphon action working, but once going, the flow rate is quite good. Also, storing the hose stretched out (to avoid the curl that it has from being shipped in a coil) makes it easier to insert into containers. 4 stars
