That's unfortunate, maybe you have just been one of the unlucky ones that got a badly made one, I know a couple of people that have them and don't have the problems you have described, unlucky I guess.I got one and tried it last weekend. I've been using Rotors before, so I can't really compare to the older Spires.
The loader worked fine and I like being able to dump in a pod of paint without spilling even if I haven't shot the loader completely dry (an issue I had with rotors).
But I also have to say at this price point, I'm a bit disappointed with the build quality.
E.g. the power buttons sticks down preventing the loader from turning on. The clasp on the speedfeed was extemely stiff, I was half-afraid of breaking it before it finally started working. Yeah, these will probably get better once it's broken in a bit but at this price I don't expect to get something that doesn't work 100% straight out of the box.
There is a new upgrade ring out you just need to contact Virtue & pay $10 to cover postage, this is the new ring. hope this helps.I will also add that at £40 for the SF speedfeed im EXTREMELY unhappy that there is gap enough between the teeth to spill paint... this was not an issue on the 200 but Virtue took a backstep and made this worse with their "updated" loader.
