+2!!! They are very nice to have! Mine is about 35 years old now (it was my grandfathers) and has a separate reservoir for fluid and the pump action! Other than a little leak and the hassle of handling 2 parts connected by a hydraulic line.... It's still just as easy to use today as it was those many years ago!
