I’ve had a 4 for a few months and it’s a decent improvement on the three. However, I’ve had to drop to the demi to get the benefit of half units during the day and this has the same style and design as the three.

I think the 4 is the closest thing yet to the original thin Novopen but with improvements over the 3 such as quick cartridge replacement and being able to adjust down as well as up and a much smoother single click delivery.
