I haven't ridden one further than around the block, so my opinion is mostly formed on the basis of the A-to-B magazine review and knowing something about the performance of some of the components e.g. the plug-in pedals with integrated pedal holder. That isn't really enough to back my judgement regarding a fairly expensive bit of kit.
Lighter weight is always good for a folding bike, provided you don't lose function. The narrower gear range is ok for train commuters but a little disappointing for touring-oriented or faster riding. I cruise around in 3/4/5th on my L6 and spent a whole lot of time in 6th (50t chainring) during the 2019 Brompton World Championships. The 4sp derailleur loses both the top and bottom ends. The plug-in pedals/ sockets will wear over time. The Tubolito tubes will eventually be binned for something less fragile.
