I have an original T1 (one of my absolute favorites), 2 of the Super 6's (think they should still be in production), 2 of the Precise 10440's (whata great little go to dinner, conference, in a meeting machine) and a 16340 Precise on order.
I've had a lot of PV's and PS was one of my very first mods. I still have my original V1 and it (last time I used it) performs well but, the Super-T machines are carefree.
Very rarely do I clean or need to polish anything. I charge batts and fill carts.
They're classy mechanical works of art that perform better than anything else I've ever owned.
Customer service is as good as it gets but the best part is, you never need it.
There's nothing to break or wear. I've never seen arcing or shorting.. Nothing there to fail.
The adapter threads are stainless so, if I get a new cart that has tight threads it's not an issue. A couple of up and downs and it's ready to go.
Last but certainly not least.
David doesn't copy the designs of others, he's creative, forward looking and doesn't go start his own forum when customers have problems.
