Anyone use auto lifters? Opinions

@rjamilla- Yeah, the Safety Raiser can be a pain to position, far as holding the height you want, then trying to set the horizontal while tightening the screw. I stretched a tiny O-ring around the body, to hold the vertical adjustment, which massively simplified the procedure. It was a snap to set, after that. Never have had to readjust one and it’s very gentle habits, have been most comforting, given the low mass and seeming delicacy of my Magnepan Unitrac I. It would be hard to trust another design, after so many years of reliable service.

Sleepwalker, I meant a stand alone optical lift you could use on any turntable. 
Jameswei, I see on the internet people put a little strip of the soft side of Velcro on the arm where it contacts the tonearm. I would think that would get rid of the "clunk." I shall see as I ordered one off their web site.

Yes, adding the velcro strip was one of the modifications I made.

I will certainly do that but I am a little mift. I have not heard anything from the Expressimo web site regarding my purchase. These lift are only available now from this web site. I used Paypal to pay for it so I am protected.I have not had even a confirmation of the sale which is a little unusual now a days.
