Very, very comfortable to use. Quality construction, very soft and squishy grip, while making the pen very easy to hold, does not interfere with use. If anything, having a pen this comfortable makes me want to use it more. My favorite ballpoint, when paired with 0.7mm BRFN-10F blue refill.

I bought this kind of pen based on the reviews here on Jetpens, and now if I don't have it with me, I can feel my fingers itching for it! I just wish the blue accent version came with blue ink. Normally I'm not a klutz, but I tried to replace the refill with blue and couldn't for the life of me get the pen back together! It didn't look hard! Ah, well, I just ordered the all-black version and kept all the pieces of the blue one in the hope that someone can fix it for me someday!

While obviously similar to the the other Center of Gravity pens, this one seems to have a softer grip, which is excellent, and more beveled at lower end of grip which is nice too. Uses either the COG or older BRF15/25 refills. I agree with previous reviewer, a switch to the Acroball refills would be terrific. But still the best of the Ctr of Gravity pens, IMHO.

This pen makes writing with my arthritis alot more enjoyable and pain free

Dr Grip is a nice pen. Good ink flow. Comfortable grip.
