Nano Pen

Great attachment for my keysmart Pro. Would have gotten better reviews but for poor customer service as I have repeatedly reiterated that the keysmart pro I have, barely 6 months stopped working a few months ago; light works, but find my phone function is now non-existent. There has been no acknowledgement or response to my inquiry as to how to troubleshoot and resolve this

Awesome pen!

I really liked the pen in the short time i had it. Wrote well small, cool magnet cap. Unfortunately i lost it after 1 day. I plan to buy another, maybe 2.

Love it!

It’s my favorite pen to carry on me all the time! Magnets strong and pen feels nice and hefty (despite its tiny size.) refills are available and I have no issues with how it writes. That being said, I’d change a few things:
The magnet in the cap. Altho strong, it can eventually stick to the pen tip coming out of the cap (I glued mine back in and it’s been working a long time)
Also, it would be nice if the back of the pen were magnetic as well so you can keep the cap parked there when in use.

The refill. I like how refills are avail, but there is no tapering on the refill & the hole in the tip of the pen is the whole diameter of the refill. It’ll never happen, but hypothetically the refill can come entirely out of the front.

All that being said, I love it. Thanks
