V2 pen dose accuracy?

Hong Kong Yanpep International
V2 improved over V1 on dose retention - the jumping-back issue still shows up in reports. Holding the position until fully released after each dial is the standard fix.
 
The click feedback on the V2 is the specific thing that's hard to reproduce in pens that use smoother mechanisms - the discrete tactile confirmation of each dose increment is genuinely useful for dosing accuracy, especially when you're calibrating in small steps. The 'better' pen question usually comes down to whether the form factor or ergonomic improvement is worth trading away feedback you already rely on.
 
The Convipen reliability pattern tends to hold across low to moderate usage volumes - the mechanical lock-up issues that come up in the community are usually at very high click counts or with certain cartridge brands. keeping a backup pen type on hand is the practical hedge for when any single pen model develops an issue, since mid-protocol interruptions are worse than switching between pen types intentionally
 
What actually makes a pen automatic versus manual? Aren't they all basically automatic since it's just pushing a button either way? Never actually used one myself yet, though a few are on their way, ordered a handful of a newer version.
 
By the way, tested my newer pen model and it was spot on at 10, 20, 40, and 60 units. Still prefer my other pen for higher doses though, easier push. Probably going to stick with the newer one only for smaller amounts, 30 units or under.
