Not used it, but did find this review and similar question on a different model site

My advice is probably give it a miss. I spent ~£40 on a "kit" and then ended up needing to get a better compressor as well as a better brush.
For just having a little dabble it might be ok, but if looking a for anything better then maybe look for an iwata brush and a compressor with water trap and air tank
