There’s a few of this style pcp compressor to choose from but after a lot of research this seemed to be the best combination of reviews and price. I think it was a good choice. It will fill two guns to 210bar in a few minutes each. You have to keep a eye on temperature, not let it rise over 80 deg, but I pause filling for a minute or so when it gets around 72, which is once per fill (so fairly quickly) to avoid stressing the pump. Its chunky water separator is staying dry so far but moisture is blown out of the bleed valve when opened, apparently it helps to keep the gun higher than the pump when filling. So happy with it in that respect. It is noisy, when the compressor is engaged it sounds like an old diesel truck engine but it works very well. I am really happy with this purchase and have recommended this 350W compressor to friends at the range. It doesn’t disappoint.
