I've used my old LIDO1 for a few days now and have some thoughts.
The LIDO2 is great. It feels good in the hand, the handle is nice, it grinds fast and easy, little to no static cling, a great machine. The adjustment rings take some getting used to, I was afraid of locking them too tight perhaps, and they did move from time to time. I'm sure some more time would have solved that. Also I definitely did get some shrapnel popcorning out the top. Not a lot, maybe 2-5 bean slivers or chunks per batch. Not a huge detraction.
I've gotten used to my LIDO1, made my own silicone cover for popcorning, dealt with the static (always an issue in my climate anyway), and have managed to take its faults for what they are. It was built by hand in the USA, which is cool, and is still better than most grinders I can afford. Perhaps a few years ago I would have sold the old to get the new but for some reason, right now, trading up doesn't appeal to me. Plus the wait time right now for a LIDO2 is unappealing. That may change, all things do. Have fun!
TL;DR New LIDO is great, but I'm keeping the old LIDO for now.
