Yep had one for 18months and only stopped using it due to reverb coming with new bike, been on another bike for 12 months and still going strong.
Has the usual problems with cable actuation I.e. Clean and lube the cable every few months and tighten bolt etc in the head but that’s no major issue, and whilst doing that unscrew the top collar and have a good clean and lube of all that as well.
Every 12 months or so take the bottom out, the cartridge unthreads clean all the internals and grease and reassemble. No service manuals I could find so its a bit DIY but fairly simple once you get used to it and a lot cheaper than a reverb to buy and maintain.
Oh and bizarrely I use a pair of beaters from a kenwood hand whisk to open the bottom up, put the pointy ends in opposite holes, cross over and twist. Would be simpler to use an appropriately sized socket and grind the sides flat to leave 2 prongs.
