Well, I received a dropper post recently and installed it yesterday. I haven't done any lengthy rides yet, but just experimenting with it, it's a game changer for me. The device overcomes one of my biggest issues while riding around town. Either the seat is too low for decent pedal assist, or too high for stability while stopped, with a high center of gravity while on your tiptoes.
The kit I bought came with two complete style of levers and the required cable. Not too pricey at $110 inc. free shipping and no additional parts required. I mounted the lever on my left bar under my phone mount and is very accessible to my thumb. I can now just swing my leg over the seat to mount my bike, then flick the lever when in motion to raise it to a decent leg extension for pedaling. Press it while seated and stopping and it drops down again.

I'm in my 70's, but fairly fit and flexible at about 6' & 160lbs and this addresses my last nagging issue with my
Lectric XP rides. I'll try and get some pics today to try and illustrate the difference in riding positions, but the dropper travel for this model is 125mm, or just slightly under 5". Maybe use a tape measure to see how much difference that could make on your bike and riding comfort.
