I needed a mixer for blending resins. I looked around and most mixers were around $1500. This price was fantastic, just was not sure if it would work. It is working great. This unit has a high shear blade that I needed for resin mixing and being pneumatic I don't have to worry I need to mix a volatile resin that I could have fire. It it could be a little sturdier, but I am very happy. It is very quiet running from my compressor line. I use a couple of bungee cords to secure a bucket to the stand. It did not have any documentation, but I requested it from the company via Amazon and they sent it within 48 hours. Great support from the company.
