I used it for the first time today.
PROS:
* It was very easy to setup IF you don't use the included manual. Head to Youtube for instructions.
*It worked.
*Appears to be high quality.
*Very quiet pump.
CONS:
*There were no instructions for adding the oil, assembling the pressure gauge, or snipping the plug on top of the gauge.
*Oil container did not have enough oil to fill the pump. When I asked about it, I was told to go buy some #46 pump oil. I knew there wouldn't be enough after viewing several YouTube videos.
I used it to degauss the epoxy resin before pouring it. It worked perfectly. There were no bubbles in the pour. I vacuumed three times, each time torching off the bubbles. On the third time, I added color, torched off the bubbles, and poured into the mold.
I would give the manual and assembly instructions a ONE STAR, but that is not totally fair for the overall rating, because it does appear to be high quality and works well with little effort.
I would recommend the chamber, just not the documentation.
