Things I liked:Can be used for filling 3000psi Paintball HPA tanks without the need to purchase additional fittings. Things I would have changed:Better instructions:
The pump came with minimal instructions. No mention if this pump is capable of continuous use, or if you must only pump for 5 minutes then rest for 15.(I am assuming the latter, just to be safe.)
And a couple minor things...
The bleed screw, although fully functional, takes several turns to open completely. A bleed valve that opened with a 1/4 turn would be a nice luxury.
An intake filter with a replaceable paper element for use in dusty conditions would also be a nice addition. What others should know:I cannot comment on how this pump works with the Benjamin Discovery, as it was purchased for the express purpose of filling 48/3000 Paintball tanks, which it seems to work well for.
When filling a 48/3000 HPA tank, 5 minutes of paced pumping will give around 250psi increase.(will vary with tank size)
The product description states that it has a "Moisture filter", but it appears to only allow the moisture to condense in the base and then be expelled when the bleed valve is opened.(There may be some sort of internal filter, but I have no intention of disassembling it to find out.)
I have used this pump to fill 4 tanks a total of about 8 times over a 2 week period with no failures of any sort.
In summing up, I would recommend that it not be used in dusty conditions, but
for the price it seems like a well built pump.

Things I liked:The out-of-the-box compatibility with my Marauder. Things I would have changed:The quality, reliability and warranty. The pump lasted a very short amount of time, freezing in the up stroke position. What others should know:I'm currently waiting to see if Crosman intends to back their product or not.
For what it costs, I feel it should be better made than it is. I can understand now why Crosman only warrantees these for ninety days.

Things I would have changed:Make it reliable. I have had this pump a little over a year. This pump lasted a few months from the factory and I have been struggling with it ever since. The final stage o-rings go out like clockwork. I seem to get between 6 and 20 charges on a Discovery out of a set of o-rings. The manufacturer is Sun Optics. Duane at Sun Optics seems to want to make good on the product but has yet to be successful. He has replaced the inner tube, provided a desicant filter, and sent me countless o-ring kits. I can practically rebuild the pump in my sleep at this point. Duane is supposedly working on a new carbon fiber o-ring to improve reliability. I believe there is a basic design flaw or manufacturing tolerance problem with this pump. Turn-around time from Sun Optics on replacement parts is generally a week or two during which time you are dead in the water with respect to shooting your rifle.
What others should know:If you like wasting money or if you enjoy rebuilding pumps more than shooting then get this pump. Otherwise, I would try the Hill Pump or one of the tank set-ups. I believe the Airforce pump is also manufactured by Sun Optics so beware. Google Sun Optics if you want to see lots of other complaints from people with similar problems. I'm really surprised the average rating on this pump is so high.
