So how exactly are they not worth purchasing over other spool valves?
I currently shoot a nice shocker and am a huge fan of luxes, droids and clones... but that doesn't mean the 2013 demon or even a v3 vapor isn't worth the purchase, especially for the price they sell at nowadays.
I mean you can pick up a perfectly fine v3 demon or V3 vapor for around the $500 and have an amazing shooter at a great price. I'd take either, but that doesn't mean I wouldn't consider a VX or a luxe in that price range also. I'm all about personal preference, so choose whatever tickles your fancy.
I will say this though. My first Demon was probably the smoothest marker I've had and I was pulling 10-11 pods off of a 68/45. I was waiting on the field while people with egos, geos and Dms had to go to the fill station... how is that not a worthy quality? Sure the overall build quality, feel, and styling could have been better, but the demons did shoot fantastic despite all that.
As for vapors, sure, they had more issues than not. I must have been doing something right when I had mine, I guess knowing how the marker works goes a long way when it comes to maintenance and adjusting the settings, pressure, etc. There are people who really do like them, and there are people who hate them. Take it for what it is, but I really liked mine. It just always worked and shot great for me.
