We have a bench unit 1500 Apeks. Our experience has been uniformly good with both the machine and the Apeks support here in Colorado very similar to what SoCalOilMaker has stated above. Unfortunately we had to close our business (making CBD oil from ag hemp) due to regulations, etc from FDA and FTC making this a tough product to legally sell. Apeks solved the main problematic issue which turned out to be a balky solenoid valve that has since been bypassed altogether. This machine now performs flawlessly every time. Typical results are about 10% recovery (9-10 gr concentrate from 90 gr initial material). Apeks discontinued this smaller bench top model but last price was $39K for a new unit. We are offering ours for sale along with all tools and everything else (except CO2 tank which can be had from any local welding shop) for $25K negotiable if anyone is interested. Pics and more details upon request.
