I really like this airbrush!
I am a 3 week newbie to this hobby and started with a Master G233, returned it, a $15 EBay Airbrush - stuck with it, and a Paasche Talon, which I returned. Fed up with poor quality, I bought a H&S Infinity CR + and really like it.
I saw good reviews of Mr Hobby by Barbatos Rex and Mikes Brush on YouTube so I thought I'd give these a try. I bought the PS-270 (O.2), PS-289 (0.3) and PS-290 (0.5) Trigger. So far, these are REALLY great airbrushes.
Benchmarking this 270 against my H&S, I'd say they are somewhat on par as far as build quality and atomization of paint. Mr Hobby is in the same league. I find the 270 sprays really smooth, but on fine detail with the same nozzle, my H&S Infinity, with my limited skillset, out performs it. But, I like the trigger pull and functioning on the Mr Hobby BETTER than my H&S. I have more reliable control. And this has a Mac valve on the gun body. Sweet!
The 270 seems to clean up easier than the HS. The nozzle assembly is smaller, so I don't get much paint build-up on the front end, and the cup area cleans a LOT easier. The HS nozzle comes completely apart easier than this, but the 270 seems to clean up so much by running cleaner through, I didn't need to take the front cap off yet, I pull the 270 needle and its really clean. Each tool has its job to do, and this PS-270 does it well. If you are new to this hobby like I am, Mr Hobby is a great place to start. I got my 3 MR Hobby Airbrushes for about what I paid for my HS InfinityCR+ 3 in 1. Although the H&S is (IMHO) a better quality and performing tool, it is reflected in the pricing.
I'd rate this Mr Hobby PS-270 as a SUPERB value. It's a keeper! You'll be VERY happy with this airbrush- give it a try!
