The Worrgas Adjustable system did not leave my A4 Fly starved for air. It is very quick to recharge and has a high flow. The overall weight of the system is very light, making my whole marker set up even lighter. Finally the size, the first stage regulator is the tiniest reg of its kind of I have ever used. It might be two inches long but I don't think so, gives you a very small set up even if only mounted with a rail. It has a very friendly "dovetail" mount making it easy to mount on almost anything.
The only weakness I could detect is a possible quality control issue. The first time I had the tank filled the main o-ring in the reg blew. It mihgt have been a defect in the o-ring but it left a general bad taste in my mouth. Also I have to replace the HP fill gauge because it has somehow gone bad, not giving me a relable accurate reading. I was playing during a work function and went out for one of the last games thinking I had a good 2k psi left....not the case I was pretty much dead empty. Oh well, no biggy!
Conclusion:
I strongly recommend this product, I think that these weaknesses are isolated, the system is excellent otherwise!
