Never actually used it but tested it out in the bath under the water and works great. Only thing that is missing is the thick rubber sealing ring to go in between the nozzle and the tank (which lets out air). This is a cheap fix ( £2 on ebay) and will work great. Brought it a few years ago and never got to use it. Whole set cost me around £300 but willing to let it go for about £275
