Familiarity: I've used it several times
I just installed this dropper on my XC/trail/endurance race bike, which previously had a 125mm Fox Transfer, because at the time, it's the only one that would fit. This has the least overall insertion depth of any dropper on the market, and I also saved some weight by switching.
I oped to get the 150mm Oneup (thinking about getting a Revekate seat pack and need 6" of tire clearance), but could have probably gone with the 180mm and put in a shim or two, which would have allowed me to slam my seat post to the frame. That's the great thing about this dropper - for riders who are shorter, or who are in an awkward size/frame range, this allows them to get the most possible drop and avoid weird situations. I've met short people who actually have to lower their dropper ever so slightly when they raise their seat to climb. This would fix that.
This thing has been reliable, was super easy to install, and will be very easy to self-service (replace cartridge, lube, replace actuator cable,etc). Well done oneup! Only thing left is to design one for 34.9 seatpost diameter.
I've ridden the reverb (hated it), Fox Transfer (liked it), and Bikeyoke (loved it). This is just as good as the Bikeyoke so far, and much less $$.
