I think I would recommend them but they're definitely not perfect.
I have had some (rare) reliability issues and I really wish they had removable 18650 batteries for long night rides.
The radar is a https://www.garmin.com/en-GB/p/698001 which is useful to let you see and know the speed of cars approaching from behind.
These are great. Simple bit of kit that works well.
The only thing that really drives me nuts about them is that they have a tendency to come out of Airplane mode by themselves. Bluetooth gradually drains them flat if I don't keep them constantly plugged in.
Since I've never really got the Ant+ networking to work reliably either I could probably do without any wireless features.
Oh and I got mine on sale for about half what they normally go for
...and put the savings towards another bike obvs. (n+1) (s-1), etc :D
Recently I’ve attached my go pro and it being much newer is better and digital stabilization but the battery life isn’t great.
So I usually ride without. But I have a cell phone in my pocket..
