Does anyone use a Cannondale bike with SmartSense? Real world feedback??

Musing about a Synapse as there seems to be various models on sale at the moment.

But most seem to have (ugly, IMO) SmartSense battery/radar/lights integration.

I’ve read DCRainmakers review from approx 18 months ago and it seems the main benefit was one battery to charge rather than multiple batteries BUT many comments about the on-board battery being way too small (max ~4hrs run-time)

So, what are the real world benefits???

(And, assuming it’s not-for-me, is it likely easy to rip out all the components?)
