This is the single-lever paddle from Vibroplex. Purchased NIB.
There are a LOT of adjustments on this key! About eight or ten things to fiddle with. This seems unnecessarily complex for a single-lever paddle action. The adjustment screws are coarse thread. There is way too much slop and play and backlash in the adjustments. The only document that came with it was a parts blow-up schematic. No adjustment explanation.
As-received, it was useless. Everything loose and flopping around. Pivot arm rattling around. Contact pads not even lined up. It's like they just haphazardly threw it together as an afterthought, and tossed it into the box.
IF you ever get it adjusted to a setup that you like, try not to be too rough with it or the adjustment locks will work loose. I can never seem to be able to adjust this thing the same way twice.
On the other hand, when I do manage to get it to where I want it, its works well and action is smooth; and, at least until the adjustments work loose again, I like using it.
