I’ve just picked up a Duet second hand. How do I know if it is a V1 or V2?
On the first sight, it is very hard, but the Duet V1's hood is a tad rounder. You can, however, tell based on the folding system. The Duet V2 has a mechanism that allows even for one-handed folding, however, the V1 needs two hands. The V2 also has newer safety belts without the extra fabric sticking out, so - sleeker. And - the fabric is nicer, less creased on the V2, plus the wheels of the V2 version are wider than the 1st, though that you won't see without having the two version side by side, I guess.
I would probably focus on the folding to be clear about the version.
Your -very berry- Eli.
