Anyone use auto lifters? Opinions

I must be getting lazy in my old age. I keep wishing someone would raise my tonearm for me. Sometimes you are just involved in something and putting it down to lift the tonearm is a pain. There are several auto lifters on the market. Does anyone have any experience with these? Do they work reliably and are they easy enough to trip that you do not have to worry about you tonearm and cartridge?
I have an old Thorens lift which are being sold under the Q-up name now.  I've had it for years and moved it from table to table.  It can be height adjusted.  Cost is around $50.  I can't go without now.  

I too am getting lazy in my old age.
Has anyone ever affixed the Q-Up using BlueTac so as to not have any residue left on the plinth, when moving to another table?
I don’t use them. But I have a friend who uses the AT Safety Raiser. He bought one when it first came out and it works like a charm.
AT safety raiser works great. Takes a few tries to get it placed perfectly 
Auto lift and return is an important feature to me, so I bought and restored a vintage semi-auto turntable. I don’t understand why the feature is not available on new turntables any more. 
Thanx for the help. It seems like the AT unit gets the best reviews. It is also pricey at $129 amazon prime. The Qup is rather large and certainly will not fit on my SOTA. It might on the SME but I tend to us the SOTA more.There are several versions of the AT lift from a cheaper Chinese version to the Little Fwend which is almost twice the price. Has anybody used the Expressimo Audio lifter? I love the simplicity of design and it looks like it will fit anywhere. It goes for $100.  

Sleepwalker65, the audiophile community shunned automated tonearms thinking that the mechanisms would cause a deterioration in sound quality. Plus many audiophiles want to mix and match tonearms and tables making mechanized tonearms impossible. Stacking records was considered an absolute no no. I think an automated turntable with excellent performance could be done but the market just is not big enough to support it. All those folks interested in convenience are just streaming and have no interest in vinyl. But we know better:) 
Greetings.  I too have used the Q-up with good results. The product works as advertised.

I have since installed the more visually appealing Tru-Lift,  which can be finicky, depending on the run out of the record,  but lifts 98% of the time.There is a sensitivity adjustment - alas - 100% is not achievable.

Pricey it may be,  but it looks great on my TT.  Cheers.

Mijostyn I have a Technics SL-1700mk2, which doesn’t engage the arm return motor until an optical sensor triggers it. It’s like having your cake and eating it too. Because the system is not physically in contact with the arm pivot while a record is playing, it has no negative impact. And I said semi-automatic, which is only arm return and platter motor shutoff at end of play. Record  changers  like those old BSR units with crappy ceramic cartridges are taboo. 
Sleepwalker, Dual made some pretty fine automated turntables. You could put any cartridge you liked in them. The optical trip is very cool. You could imagine a lift designed around an optical sensor but it would be expensive.
Guys, thanks for joining in. I pulled the trigger and ordered an Expressimo. If the Q-up would have fit on my table I would have ordered that. I will report back on it. May be junk. I love living life dangerously.
if you've got the cash and the desire for something pretty - 

google "Tru-Lift-Tonearm-Lifter"

Tru-Lift appears to be the exact same thing as the Audio Technica AT6006R though, only at twice the price.
I did have a lift in the early 80s. It was the same type of mechanism as the Tru Lift. After several years of use the trip wire slot wore to the point that the thing would trip itself intermittently. I would suppose that problem has been designed out by now. 
My first Safety Raiser(AT6006) lasted 30+ years, before it began lifting too quickly(too speedily/not prematurely). That’s a lot of years, in which I enjoyed end-of-record-peace-of-mind, via it’s very gentle lifting habits. Not bad for the $19.95 that I paid, back in 1980. I quickly found a couple NOS/NIB Raisers, for which I(gladly) paid $120 each(2012’s price).  Once properly adjusted, I've found mine 100% reliable.    Now, Audio-Technica has re-released the piece(AT6006R), sans the lock-down wire of the old(no big loss), probably now made in China, with a higher price(of course).
@mijostyn the lift designed around an optical sensor is reality, and it came at a premium on the Technics SL-1700mk2 and SL-1600mk2 turntables. Those were essentially the thinking man’s / audiophile’s variant of the SL-1200mk2 that rap-“DJ”s are so enamoured with. 
Thrulift is an excellent lift it’s gentle and well thought out.  On lighter tonearms like the Triplanar U12 it’s excellent. The original AudioTechnica 6061 is a little more coarse in its operation - on a heavier tonearm like the Kuzma 4P 14 it works flawlessly.

good Listening 

I've been using a modified Expressimo The Lift.  Does the job, although it makes a little clunk as it contacts the tonearm.  I like that it has no springs, just a weight.  As with most others, correct placement is important.
I use two different tonearm lifts. The Q-Up is the better of the two which I've used for well over a decade. I do not have a Safety Raiser, but admittedly it looks better. But it also looks harder to position. On my Rega P5, the Q-Up matches pretty well with aesthetically. But the P5 is unique looking with being mostly black with a silver tonearm. The advantage of the Q-Up is that it slides, so it's very easy to make final adjustments where within the run out the the tonearm lifts. I don't think this is a huge advantage over the Safety Raiser, but it is easier. The Q-Up also has a few adjustments to the trigger and the lift speed.
There are two versions of The Lift (a product from Express Machining in San Jose, the guy who makes the Rega upgrade parts) listed on USAM right now, one chrome one black.
@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.
began lifting too quickly(too speedily/not prematurely).
I've have the AT "Safety Raiser", actually a few over the years, often inherited when I buy a turntable. They're not difficult to position (contrary to rumor) once you understand them. They work every time, they're silent, and the gentlest auto-lift I know of.

The problem Rodman describes (quote above) is easily fixed — it's the same issue that happens to cueing-devices over time. Add the same silicone used for cueing (it's easy), and the AT will work at the right speed again, for another 30 years.

When AT's patent expired, clones appeared. They usually lack a feature or two (e.g. adjustability). Or cost far more: you're paying for its "beauty" [sic] not functionality — it may look good in an Ad, but it's barely noticeable when mounted, Throwing money away, IMO. AT has reintroduced their original, and it's improved.

The idea of an optical-sensor with a small motor is a good one, but I've never seen one as an accessory — even though many TTs used it internally. I considered making one, not difficult — but not worth the effort, to me at any rate.
