Very nice pens, I like to use them at night to write down my dreams, these are bright enough to write in the dark without
turning on the light, I don't like getting up and tuning on the light just to write something down, so these work great.
They write smooth and easy, I am picky about ink pens so I was excited about these.
Great seller too.
These pens have white when they light up, I also have the ones that light up green, and one that lights up red.
No matter which color you choose, they are all great pens, I love the way they write and I journal a lot so how a pen writes is
very important to me.
These will always be my go to pens.
Also the refills are easy to find for these pens.

*** READ THE UPDATE AT THE BOTTOM!***
Love it.
Writes very smooth.
Build isn't as nice as it feels. Within 10 minutes of using it, the threads between the plastic pen (bottom) and the metal(?) Light(top) came apart. The pen side keeps popping loose. I glued it together and now have no issues. For this reason, I won't buy it again. I'll keep it. I do like it and use it all the time. But I'll look for a better quality pen when it's time to replace it.
***UPDATE***
Alrighty!
First off, I need to say, their response time and communication is 110%!
I originally gave them only 2 stars. As you see now I've bumped it to 5. Not because of the replacement pens they sent me. Not even for the fourth pen that was included. (I'd rather pay for the product and have zero issues.)
They received 5 stars for one main reason... CUSTOMER SERVICE!
Over a few days following my original review, we emailed back and forth. The response I received was thoughtful and attentive. They actually listened to my wants and desires out of a writing instrument. I have no doubt that my concerns and issues noted above will be addressed I am excited to see the future products they develop. I'm hoping for a heavier, higher end and more tactical pen in this format. Hint, hint...
I don't mind spending my money with someone that has customer service like this. I will definitely be ordering from them again! These 4 pens I received today will be going to friends as gifts.
Now onto a review a few weeks after. I haul frac sand in the West Texas oilfield. I'm in a very dusty environment. My glue mod has given me zero new issues. I did, however, start having issues with the light switch on top start sticking on. At first a slight tap would pop it lose. But after a while, it just stuck on. I disassembled it, cleaned the sand( I had it in my pocket while unloading the stuff.) out, reassembled it and it's working fine! I leave it in the truck now. Another worry was the life of the batteries. I'm always in low light areas and have it on a lot. Not to mention it ends up being a flashlight almost every time I have it in my hand. The batteries haven't shown any signs of discharge. I'm impressed!
I also received a personal note. I marked out some personal information in the picture below. Thank you Tony!

If you're like me and write reviews, this pen, with some black tape, is an excellent combination. You can see what you're writing without feeling like you are using a bright flashlight and disturbing everyone. My only issue though is what attaches the pen to the lighting mechanism isn't something you can necessarily just throw in your bag and keep it moving. I've done so before are, just with it moving about with the rest of my things, have had to hunt for the two sides on more than one occassion.

I like this pen light more than anything else on the market. However, they are very delicate and do not work smoothly at all. They are pretty cheap and you kind of have to pretend you are cracking a safe with the back of the pen to make sure the light activates. However, this is the only pen that performs the kind of function I was looking for, and I got 3 of them. Plus, the light itsself really does work. It is the right kind of cast for dark writing. I wrote in my notebook on a dark airplane for an hour yesterday with this pen, and I bought it a year ago. So if they don't work great, they still work well enough. I would buy these again if I had a chance to go back and reevaluate, but I do totally wish they worked more consistently.

There is more in the package than I thought and they are good so far. I use them when I am working on my paperwork in the work truck at night and early morning. So far they are working great and a big help. If you are in a hard environment be sure to take care of them. The light is bright enough to let you see what you are writing even around your hand. I have recommended them to some of the other drivers that I work with after they saw mine. Anyone working at night really should have some of these. Students could use them if the lecture halls are dark as well.
