Got a Mach 12 a few weeks ago because my old shoulders were complaining and it was the lightest wand I could find. It arrived with the new PMF one-piece slot
glide, which is difficult to push over 12 hg because the bridges between the lips are recessed. Called Lisa for a hole glide and she wouldn't take my card cuz I'm so old. I told her no way. She's given me at least two others, so I'll pay for this one. She still wouldn't take my card. Thanks, Lisa!
The Mach 12 with the Greenglides hole glide works great. Super light cuz the fat PMF glide and heavy steel lips it fits over are gone. Great suction and no streaking. Running 12' X 2' whip directly to wand from 2.5 to Devastator filter. Don't know whether I really need 2.5" from the machine for a 1.5" wand, but that's what I've been doing.
Mach 12 was dripping a little from the manifold due to an incomplete weld. Texted PMF on a Friday and had a whole new manifold with jets on Monday.
Lisa has always been fun to work with. And PMF customer service was outstanding.
P.S. I mentioned to Lisa that I was thinking about taking my Lab to the vet because she, very uncharacteristically, hadn't been eating much. (For those who don't know, Lisa does Pug rescue.) She explained that Labs can get inverted stomachs and instructed me to take her temp, palpitate her stomach to see if it was painful for her, and check that her gums were red. I took her to the vet and that's exactly what the vet did. She's fine now. Thanks, Dr. Lisa!
