Review on Fermtech Regular Deluxe Siphoning Auto by Kevin Phillips

I have used this siphon several times and found that the piston head does not form a complete seal against the inner wall of the chamber. This allows air to flow through the piston and reduces liquid suction into the chamber, sometimes there is little to no liquid suction, other times it works great. Cleaning is also a challenge for the same reason and I have never found a way to dry the item properly without leaving it for a few days just waiting for evaporation to take its course. If this one disappoints me enough, I'll look for a better siphon.
