1-year limited warranty
Things I liked:It works. It's not anywhere as near as hard as some make it out to be. It's great exercise.
Things I would have changed:The hose should be longer. It should come with a dessicant type water separator, in addition to the sump type that's built in.
What others should know:I normally use my scuba tank to put 1/2 to 2/3 of the air into the reservoirs of my B50 and 909 light hunter. Then I use the pump to finish the job. A tankful of air lasts longer, and it's quicker and easier than pumping from zero. I also use it to pump my QB78 up to 1,000-1,100 psi, using a bulk fill adapter and a female QD fitting on the pump hose. This is the normal pressure for CO2 at around 95 degrees Fahrenheit. I get about 10 good shots before POI starts to drop off. It takes 20-21 strokes of the pump to get pressure from zero to 1,100 psi. More convenient than shooting my multi pump pneumatics, and it works better in cold weather than CO2..
Things I liked:It did work about 3 times....
Things I would have changed:The price is way to high for a pump. Mechanically you'll find more stability in a house of cards.
What others should know:Buy a scuba tank. Its a headache and a thousand calls to customer service.
Things I liked:Works well. Makes me completely independent. The gauge is accurate. I have even used it to pressurize a small scuba pony tank (6 cu. ft.) - though I had to take that in stages
Things I would have changed:A longer hose would be helpful, though the standard hose works fine
What others should know:The video is helpful, especially the reminder to pause at the top and bottom of each stroke. It is a bit more time consuming but it guarantees a full pump. The pause may be as long as 3 seconds when approaching full pressure.
