Yacig Light Up Pen, Intellectual LED Pen Light for Night Writing, Two Brightness Settings, 1x AAA Battery Powered, Easy to Operate Pack of 2 - White

The media could not be loaded. 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 have used these great LED light up pens for a few years. They work great! One of the best features is that they run on one AAA battery…not those lousy button cells that other pens use. AAA batteries are easy to find and easy to replace.Recently bought another pen to keep in travel bag. The on/off switch had a problem. I had a very fast reply from their customer service and a replacement pen was sent right away.Great product and great customer service! What more could you want?

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.

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.

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