Started a thread about this on dootalk a couple of weeks ago.

Picked this up on amazon for 159. It is a 3 stage pump good for at least 3000psi. So far it functions as expected. I have yet to completely fill a bottle. What i have done is to connect a full bottle and was able to raise the pressure about 100 psi with 8 or 9 strokes. It will probably take in the range of 200 to fill an empty bottle. I'll find out in the next day or so when I do the anual test. 2 packs, will test and refill both.

Well, I finally had time to deploy and refill. It works. It is more work than I expected. Good upper body workout. It is a 3 stage pump, up stroke draws air in and compresses stage 2, down compresses stage 1 & 3. Stage 3 is about 3/16" dia. I placed the bottle as high as the hose would allow while pumping. Hoping any moisture would condense in the hose. I openned the bleed valve serveral times during the process. Got some silicone oil from the pump and very little if any water. NWS reports, humidity 44%.
Strokes & pressure
25 250
125 1000
200 1500
275 2000
330 2400
360 2700
Over all, I'm happy with the pump. My group travels out of town a couple of times a year for a week at a time. If a refill is needed it can be done without screwing around trying to find a scuba shop at 6000' in winter. I've tried the FD fill thing and the fire chief in Rexburg is very against filling. Real putz! The dive shop in Idaho falls is a 50 mile round trip and might even be open when I get there. Got a bottle filled there once in three tries. 150 miles and serveral hours to fill once...I'm done with that... dont know about the paint ball shops... I thought they used carbon dioxide, not filling my bottle with that!

The down stroke gets tougher. If you can mtn ride, you can fill the bottle. I'm old and did 2 in one evening. The second bottle seemed to fill a little faster. Felt like the pump was "broke in". I didnt hear air leaking past the intake valve as often on the second bottle. Pump does get warm. Hot if you get too vigorous. This not a fast as you can go operation. Up, pause for half second, down at a moderate steady rate. Full travel both directions.
No one in my group has to worry about a refill. If you are in a slide, deploy immediately. We will refill the same day. Also, no reason not to do the annual test. If someone from another group needs a fill, thats fine too.
If anyone else purchases this type pump, please post your findings.
