I've had my Hills pump since last July, fills my guns fine including a 480cc carbon bottle on the FX Royale. I fitted an extra inline filter more as a belt & braces guard against moisture than a necessity. I would say it is not suitable for bottle filling though, despite the claims. It gets hot, cuts out & restarts over the fill around every 20bar from 200bar to 300bar on a 3 litre bottle. Now this is how it's meant to operate but it just feels like it's trying too hard & gets too hot in the process to me. Hence me only filling direct to guns with it now.
