Really nice pen – all metal and feels good in my hand. High quality dose dialing mechanism and plunger. Depressing the injector is really smooth. Case is a nice touch, I keep a handful of pen needles in the case mesh which works great.

This pen has a metal exterior that makes it cool to the touch. It feels high quality and the case is a nice bonus. I can fit up to three pens in that case if I take out the insert; not for travel but nice to keep my fridge organized.

A great manual pen. Beautiful color. Metal, which just feels more high-end to me than plastic. Lightweight. Accurate dosing. No learning curve. The “Convi ghost click” is so soft that you might think you imagined it. I haven’t found any downsides yet.

Love this pen! The mechanics are super smooth. The big numbers are nice for old eyes. Entire order process was just as smooth and shipping was quick!

I really enjoy the weight of this pen unlike the cheaper plastic ones. The smooth operation is amazing as well! Will definitely get another one.

Smooth high quality pen. Love the look and feel of them. I bought both colors. Graphite for me and Red for my wife. Easy to use and dosage is accurate from my rudimentary home testing. Case is a bonus especially for travel. Fast shipping and great customer service. Will be using Daro Pep for all my pen and pen supply orders!

Ordering was very easy with prompt tracking and delivery. Pen is extremely nice and feels like a professional piece of equipment. Checked dosing from 10 t0 60 units and perfect. Easy to set dosing and gost click makes for very smooth delivery.
