This is a terrific manual set-up for ease of use and those who are just starting out or those experienced pumpers who just need a simple tool that works great at a moment's notice. CTC's cylinders may seem like any other but they really are better- in lightness, seal, and comfort -and you will notice right away. This is a fav of mine, easy to travel, and does a better job than most more expensive. I recommend this as a must-have adjunct if you have one of the electric pumps...
