The rigid straight bit that goes in the wine to be siphoned is a great idea. It can be seated almost on top of the sediment and, because it takes the liquid in from the top, is very good at getting as much out as possible without it being all cloudy. However, the clip is worse than useless. It is almost impossible to keep hold of the bit that is in the fermenter and then close the clip when a bottle is full. Even when closed it doesn't really stop the flow. A simple TAP (readily available from most places for about 99p) saves a lot of trouble and mess. I just don't understand why Ballihoo don't use them.
