Now, having finally spent a day getting used to my shiny new Ultra 2024 I can safely say I'm extremely impressed with it. I rank myself as a beginner, having only had two airbrushes prior to this one (one as part of a cheap Amazon set which was sent back within a week, and the other - a Fengda/Bartsharp badged generic Chinese job I struggled with for a few months - I still have but came within an ace of throwing it through a window on several occasions) I only wish I'd heeded previous advice and gone for a good quality airbrush to start with.
In a nutshell, the Ultra 2024 does exactly wot it sez on the tin. It was designed with the inexperienced user in mind and the combination of it's unique "helper" features and amazingly high quality engineering has taken away the frustrations of stripping/cleaning to clear tip-dry and constant clogging issues I experienced with the other two. I only use acrylics and had to learn about tip-dry the hard way but the Ultra 2024 makes dealing with it a breeze. A few quick stabs with a stencil brush dipped in IPA and the tip is clear again without needing to strip anything.
The low component count and unique design makes deep-cleaning quick and easy too, on the rare occasions when you need to do it. The innovative trigger design and "training wheels" settings literally force you into using it correctly and you can override them if you choose once you're familiar with it and know what you're doing.
This is not a fully detailed technical review as I don't regard myself as qualified to produce one but I'm precisely the sort of user it's aimed at. I will say however that all the positive reviews I've come across have got it dead right in that it's an absolutely ideal beginners airbrush and indeed one for more advanced users too. Price-wise, I was gifted mine by Mrs N but I've seen them for as little as £85 from reputable suppliers which is not exactly a fortune for a decent airbrush.
People new to airbrushing will always be tempted to go the cheap route initially (I certainly was) but the frustrations that come with cheap airbrushes to those who aren't familiar with them make it a poor decision. I cannot recommend the Ultra 2024 too highly, honestly.
