I have/had the pletscher. My only complaint is the single hole/bolt mounting. Eventually it rotates. Repeated tightening finally popped out the internal tube on my bike's mounting pad. After several years I took it off because my office closed and I became permanent work from home (prior to covid)and so I do not stop and park as much as I used to do. It also needed periodic/annual deep-cleaning and lubrication but probably they all would as I was year round rider and winter generates a lot of dirt, but dirty internals meant I had to use more force to move it to the riding position which leads to easier rotation on the single mount. I think it's a great piece and my situation was unusual. But, single hole mounting is a pivot point and if I ever remounted it I would add a second pin or bolt to anchor it.
