| Works, but will not produce enough vacuum for some usesOctober 19, 2015 Only produces a weak vacuum; good enough for some purposes, but not nearly as good as some other hand pumps. It would be adequate for priming a system with fluid or bleeding brakes, but not for evaporating liquids or demonstrating glow discharges. Three StarsSeptember 10, 2015 ANOTHER experiment item. my 7 year old son likes itJuly 16, 2015 an interesting toy but does not achieve the vacuum i need for my research good vacuum, made for a man's handMarch 30, 2013 It works well. Gets a good vacuum and holds it pretty well. I bought this to replace the flimsy, toy like hand pump that is sold with a goat milking unit. I was tired of replacing the $100 pump every year because it is so flimsy.Would love this, even with a stronger pull, but the finger grooves were modeled on King Kong's hand. | | | | |

| Save your money.January 13, 2016 Can we say VERY bad off gas? Will not pull but 75% of it's total dial indication pressure value. Won't buy this again. Gauge broken on delivery and likely overstating the vacuumDecember 30, 2015 The gauge needle was stuck at -300 mmHG right out of the box. After a lot of pumping, the gauge reads -700 mmHg (which is actually -400 mmHg), which seems pretty respectable. However, water barely boils at 90C so I am strongly inclined to think that the gauge is overstating the vacuum. Two StarsApril 26, 2015 Junk | | | | |

| One StarMarch 29, 2016 I sent this back. It didn't even work when I pulled it out of the package. Worked well for a few months then tiny cracks formed and wouldn't draw a vacuum.March 9, 2016 Worked well for a few months then tiny cracks formed and wouldn't draw a vacuum. I took it apart to inspect the check valve housing and found a few cracks close to the screw holes. I think my replacement will be a higher quality metal unit. Cannot recommend.February 9, 2016 I've used this pump about 12 times and over time the vacuum was getting less and less all the time until now, there's zero suction. It's never been submerged, dropped or mistreated so obviously it's a quality issue. The gauge never did register properly so fortunately I didn't need specific or accurate readings. There is also a 30 day return policy, so I cannot recommend this for any reason. One StarOctober 1, 2015 The gauge would not return to zero - stuck. Will be trying to return it. One StarSeptember 30, 2014 It pumps once and the plunger doesn't return for a second pump for too long. It's cumbersome to use. | | | | |
