My first pen that wasn’t sketchy aliexpress junk. Reliable dosage and operation with a satisfying click once its finished. Very happy with the pen and the vendor.

The button for dispensing is on the side rather than on top. Makes dispensing easier when in awkward angles.
Dispenses liquid quickly. For those that tried the Gansulin/Convipen, it’s faster than that.
It’s actually pretty smooth but the pen feels kinda bulky to hold
Purchase and shipped the same day

Good pen, good accuracy. I am not a fan of the side trigger, I prefer the Convi.
