Thanks Jim, yes, you probably saw my response to someone on YouTube who asked why they might want to replace their existing compressor with this one... well, I have no idea why, unless your existing compressor is taking up too much space.
Perhaps I should have made it plainer, but of course the selling point of this unit is its very small size, and I think it is pretty small, and light, so yes it is very portable. Perhaps portability isn't a big deal for most modellers, although you might still like the fact that you can stash it away in a small space if you happen to live in a small flat. Obviously one market for these things is people doing nail art, and they may be more likely to be mobile.
So taking the small size I guess I focussed on what you get and how it works. I agree, and did point out the issue, over the moisture trap; I guess it was designed this way in order to keep the unit size down to the minimum, and perhaps the same is true of the bleed valve.
So I did also make the point that this unit comes out well in terms of performance figures, at any rate, when compared with one of its direct competitors from a well known brand, and by that I mean another similarly small sized portable non tank compressor.
Hope that makes things a bit clearer - but, yes, feedback is good.
