That,s the one I have. Unfortunately mine packed up after only two hours use. And, to make matters worse we can,t buy spares here in Britain. I have since found out that the vendor I bought mine from has a bad record as a scammer , selling all sorts of goods and either sending sub standard goods or not delivering the items that have been ordered. A warning to all prospective buyers in the U K , don,t buy from anyone operating out of Portsmouth. The Americans on the other hand can buy every part of the machines through Ali Express.

Yes mate, I had topped up a couple of bottles and a rifle or two. Total running time, around two hours. I was topping up my mates, bottle when i smelt burning and noticed the gauge pressure had dropped and the head gasket was blowing. I removed the head and the high pressure piston rings just fell out, in pieces. Trouble is, i sent a return request to the vendor and tried to phone but i,ve not had a reply. I googled the name of the vendor and it came up with three different names operating from the same unit. One of them sells dresses and the feedback is terrible. Indeed some people are saying it,s a scam . Worse still spares are not available in the UK . I have got the thing running again but I doubt it will last long. To say i,m p....d is putting it mildly.

Well i,ve given it another chance and, like I predicted, it packed up again. Firstly I managed to put 15bar into an old, spare bottle with no problem. Then, just now, I attempted to top up another bottle and it seized up solid. I,ll have to walk away  for now. I,ll tear it down again when i,ve calmed down. Trouble is, i,ll still be stuck with the spares problem.

Shiiiiite.

I've learned through experience that walking away from an issue until you are fresh and motivated is the best policy Mel.......not point in making matters worse when you are angry and frustrated, and just want to take a hammer to the bloody thing!!!

Sure you get it sorted in the long run mucker. ;)

bagga, it needs some improvements to its cooling system as it generates ALOT of heat, i had the idea of making a closed loop system bit like a car cooling system but with 3-4 heat exchanges, 1 to cool the head, the rest to cool the air transfer pipes, the heat exchanges are just copper pipe in different size coils that fit inside each other which fit in a bucket of ice water, the pump fitted inline so it pumps antifreeze around all the system. i have seen radiators  https://www.google.com/search?q=computer+radiators&client=firefox-b-d&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjsm-ed8qLjAhV1lFwKHf6VB6QQ_AUIESgC&biw=1756&bih=914 which would work without the bucket of water.
it also could do with a better moisture trap to dry the sit before it gets into your gun/bottle
