I had a Lyman DPS (?) - was Generation III, I think - worked fine - at least when the throws were compared on my Hornady balance beam scale - but about effortless to use. Then, after some years, it started throwing "error" or "re-callibration" signals - at least it was smart enough to know it did not like what was happening. I would go through the re-callibrate sequence and it would repeat that error in a few more throws.
I have since got an RCBS ChargeMaster Lite - it has been plugged in continuously, since I got it in Oct. 2021 - seems to run fine. But the old balance beam scale and powder tickler are still set up on the shelf above my loading spot - I think both that Lyman that I had and the RCBS that I have, work much easier - especially to throw say 50 or 60 loads at a session - but I am not convinced they weigh any more "accurately" than the beam scale did - which, I suppose is to say, I think they throw "as accurately" as I was doing with the beam scale and powder trickler. For some reason, I am under the impression that both the Hornady beam scale and the RCBS ChargeMaster Lite are claimed to be "accurate" to within 0.01 grain weight - I might be incorrect about that. Many or most of my powder charges are intended to be thrown within 0.1 grain - so like 43.2 grains - so if I am correct about the "accuracy" of these scales, my true weight of the charges might be 43.19 to 43.21 grain - using either system.
I did notice in the User Instructions for both electronic ones - they want the power to be on them for some time - like an hour (?) - in order to "stabilize" their circuits or something - an aspect that is a bit different than the beam scale which seems to be ready to go, instantly. However, at least for this RCBS thing, I can not say that I had any hiccups or surprises, so long as I followed the User Instructions.
I have heard and read of issues for some electronic scales being interfered with by stuff around - likely why I have a four foot overhead LED light instead of any fluorescent lights in this room. My cell phone and laptop are in here about all the time, though. Both easily pick up the LAN signals from the printer in the house, or the various neighbour's LAN's. Once I found that what came off the electronic scales weighed the "same" on the balance beam scale, I did not worry about interference any more - in here.
And I am aware there are more expensive and presumably more "accurate" electronic scales and powder dispensers available to buy - like FX120 (?) - I am just not a good enough shooter, nor do I own the higher end rifles, to feel they are worth those extra dollars for me.
EDIT - I re-read your header on your post - you were asking about "tricklers" and my reply was mostly about "scales" - but the Lyman DPS and the RCBS ChargeMaster Lite are both, at the same time.
