My first purchase here. Purchase was simple fast tracking and delivery. Pen was spot on for dosing. Checked all 10unit doses. Feel was solid and smooth

This pen is like a v2 without the open cap, and is built VERY well. It’s what all v2 pens should feel like. This is a fantastic value for the price.

Excellent affordable option, nothing fancy but dose was right on the mark. Loved the quick shipping

This and the Ergo 2 are my new favorites. The plunger feel on the Biopen Flexi is a little smoother than the Ergo 2, but that’s about the only notable difference. The accuracy checked out and it leaves as little or less in the cartridge than a V2 pen. I can’t say anything bad about it. It’s a nice affordable pen that performs very well.

Very good open. The quality is pretty great. Especially the threads for the tips. You can tell they are solid and won’t wear out. Measured against a u-100 and it’s just as accurate
