No, the supco worked well for a couple years. I regularly cleaned it with alcohol and light blasts of nitro.
Last summer it started acting up to the point I felt I couldn't trust it.
I got the YJ used off my buddy, bought a sensor and it worked well once. It's only been used on "new" systems and a relatively new vacuum pump.
I'm thinking of getting the blue vac, but it's hard to find up here in Canada.
