Led Pen, Yacig LED Light Up Pen, Intellectual Red LED Pen Two Brightness Adjustable, Powered by 1x AAA Battery, Metal Barrel Heavy Weight, Pack of 2- Red

Got this specifically red light LED pen for waking up at night to write notes and thoughts by bedside. I think red light is better than white light to avoid disturbing sleep. Build quality feels good. Ink flows well and smooth (come with refills for each pen) The pen body is painted smooth and can be a bit slippery for a thick pen. It does feel heavy with the center of gravity just in the middle (see 3rd photo), partly due to AAA battery. Pen diameter is about 12 mm for the pen-nib half and about 13 mm for top-switch half (not including the pen clip). To write, you need to twist lower half of the pen (that is away from the top switch). But this twist is a bit stiff, so I usually leave the nib out and put in a pen holder by my bedside. There are 2 light intensities - 30% and 100%, by toggling the switch on top. It has a nice click sound (as in video). As another user noted there is some rattling sound from this switch if you shake pen strongly side to side, but not a deal breaker. Also, the red light is actually just smooth red. In the video, for strange reasons, my camera shows this poorly as some yellowish-orange glow (tried several times but same results). The first 2 photos are the closest that reflect the actual looks in person - smooth dull red. Kind of like those photo dark rooms. It comes with AAA battery installed and a protective black cap on the switch (to prevent switching on during transit). Just remember to pull off this black cap first to reveal the switch. It also comes with a tiny cloth pouch. All in all, it's a useful red LED pen with 2 light intensities and uses AAA battery. It's a bit heavy (can get use to it) and stiff-turning (use pen holder), but works well for me to jot notes in the middle of night without disrupting my sleep. Really useful and awesome pen!

I love these pens and I have an AMAZING Yacig customer service story to share - highly recommended. Here's how I use them, what I think of them, and my customer service story: I use my Yacig LED pens every week. I'm a writer and often jot down notes in places where the lights are low, like at the movies. The Yacig LED pens are subtle enough that I can see what I'm writing in a pocket notebook without disturbing other moviegoers around me. The low setting red is especially perfect for this. My movie newsletter is made better by using Yacig LED pens because now I can give my readers accurate dialogue and scene summaries of new movies. These pens are among my favorites now. Ink flows well, the clip is sturdy metal, and the barrel has a smooth feel for a professional, clean look. It's durable, too, and I know from having dropped mine a few times. The twist function for the pen tip is simple and the click for the light is quick. You'll notice it has a heft to it, with more weight than your standard ball point pen. That's to be expected, given it has electronics and a battery in it. The instruction manual is helpful for changing out the ink cartridge and inserting one of the included refills. I don't know enough about ink refills to know if they're truly a standard size, but poking around Amazon, I see others that look very similar. I appreciate that some are included with a 2-pack, adding value to the reasonable price. I now have several of these pens - not because they don't last, but because of the amazing customer service at Yacig. I ordered a red 2-pack but lost one fairly quickly, so I ordered a second 2-pack, both orders from Amazon. Because the original worked well, I didn't test the new pair for months. When I did, neither of the pens' lights worked, no matter what I tried, and I was long past the Amazon return window. I wrote to Yacig customer service asking if they had ideas or solutions and they responded in less than 24 hours. I was amazed at their response: they would mail me a new 2-pack of red pens, plus a white pen for my trouble. They mailed the replacements and TWO bonus white pens that week - that is customer service that goes above and beyond! When a small business makes things right, it's important that people hear about it. I'll add that for how I use the pens, I still prefer red to white, but the white pens are definitely of equal quality. Thanks for reading and I hope you have a good writing session with your new pens!

Excellent idea, having the light at the tip, and being red makes it easier on the eyes to see and write in darkness. I use it for writing down dreams in the middle of the night. I also appreciate the AAA battery it takes, as that's easier than dealing with button cells. It is nice that the ink cartridges are replaceable, and it includes a couple replacements, but you will need to buy more with time. They are the screw-in type. The paint on the pen isn't scratch resistant, and chips off easily. Also, the light itself has issues, blinking off occasionally, so I'll tap the pen to get it to light back up for me. These days, having run out of ink, I don't even use it as a pen, but rather as a red flashlight for writing at night. Honestly this pen has several issues worth noting, but overall, it's still fine for what it is and does.

These are perfect for writing or crossword puzzles while flying. The soft red light is not disturbing to there’s and the pen writes pretty well.

I bought a package of two. One pen works fine. The other isn't reliable because it has an intermittent connection.

I don't write many reviews, but I have been very impressed with the quality of the pen and felt the need to share. I had a hard time finding a "night vision" pen with a soft and dispersed light. I haven't been able to find another pen with this kind of functionality and attention to detail. The red light is perfect for keeping my night vision when I write notes in bed. The pen feels well balanced and not too heavy at the button end. The twist operation is well tuned and smooth, and the grip material is perfect - not too slick and not sticky. And most importantly, the light is dispersed and easy on the eyes when it's pitch black. The low setting is good for when your eyes are adjusted to pitch black, and the high setting is good for writing on a plane at night (for example). Thank you for the great product, I hope you can stay in business and continue producing other products with great quality - it's what this world needs, to stop producing garbage, and make products that last a lifetime. I expect this to last forever, I've dropped it a few times on hardwood and was surprised nothing broke. I was also surprised how quickly it came as well.

UPDATE: this company saw my review and reached out. They provided me with another set and allowed me to keep the working pen. Great customer service! The idea of this pen is awesome! Really was looking forward to not having to use my dome light at night during work. After opening the pens and trying them out, one of them never lit up (even after trying all new batteries) and the other lit up but not reliably. When it worked, it would flicker and sometimes not turn on if it didn’t feel like it. Disappointed in the amount I spent for regular pens since they don’t serve their function.

I do a lot of night writing and this is just the thing i was looking for to help me do that! Pen has a nice feel to it the ink is smooth to write with and i like the idea of just replacing one AAA battery instead of fumbling around with 3 button batteries. Red light is enough light to see what you are writing well but does not wreck your night vision or bother people near you. Product also comes with extra ink refills so no need to stress about finding and ordering new ones. Also the button that turns the light off and on came with a little plastic cover that will be great to keep on the pen when it is not in use to cut down on the chance it turns on in my bag and runs the battery dead, so i appreciate that as well. Great product!
