First the biggest disappointment. The description is false and misleading!!! These are NOT Fluorescent Inlays, they are YELLOW printed letters on a sticker. They will NOT glow in the dark. I left them in bright sunlight for 10 hours to test if perhaps phosphorescent and NO glow. Phosphorescent materials may appear to glow for several seconds up to a couple of days after the light has been turned off. The reason phosphorescence lasts longer than fluorescence is because the excited electrons jump to a higher energy level than for fluorescence. I then used my UV flashlights to test for Fluorescent paint, also NO glow. Fluorescence, uses a material that glows under a black light, but stop glowing once the ultraviolet light is turned off.
If you just want pretty stickers on your lap top that are bright in the day, these are fine. Plenty of symbols.
The enclosed LED light is a marketing gimmick to light up your keyboard since they are NOT Phosphorescent nor fluorescent. Its a bright LED, but cant be turned off, you have to remove it from power source to do so. A rather limited use. There was a nice tweezers enclosed to make the sticking easier.
Overall, know what you are getting. These sellers need to hit Science 101 before they make these false claims.
If you want some phosphorescent stickers, I also got these on Amazon: [2 Pack] English Keyboard Stickers, FORITO Glowing Keyboard Letter Stickers for PC Computer Keyboard/Laptop Keyboard/Desktop Keyboard -Glowing Edition.
These have limited symbols and the yellow part glows outlining the letters. The longer you sunlight/house light charge them, the longer they glow in dark.
Hope that helps.

Highly Visible Keyboard Stickers that do Glow in the Dark
Reviewed in the United States on July 10, 2020
I installed this Glow in the Dark Stick on Keyboard Kit onto an older HP Laptop that the lettering very poorly printed on the keys from the factory. I have attached several pictures of before and after installation. It took me less than 30 minutes to clean the keys and install the stickers. The stickers appear to have the same semi grip texture as the factory HP laptop keys. I used a lighted desktop magnifying glass and the included tweezers to make the installation easier to align the stickers onto the keys for a cleaner look. The kit also comes with a USB light you can plug into the side of your laptop that does work quite nicely when you are sitting in the dark and need the extra light. The Key Stickers do actually glow in the dark and are also illuminated by the laptop screen which makes the keys easier to see. I bought this kit to try out for myself to see it actually works and it does work as stated. I have a family member that has Glaucoma and has a hard time seeing the keyboard and seeing in low light conditions and this kit is perfect. Less eye strain and less mental frustration. This kit is designed to fit several styles of keyboard layouts from Laptops to Desktop Keyboards. You just choose the stickers from the sticker panels and start sticking them on and in no time you have a really nice highly visible layout for those people who really do need the extra large print. The price of the kit is very low cost considering you are getting the lettering kits for multiple keyboard layouts, installation tweezers and a USB light and if you have Amazon Prime you get free shipping. It's really a super deal. If you have someone in you family that has vision problems I highly recommend this kit.

I'm a teacher online and use my keyboard quite extensively, thus the original lettering is worn but the keyboard itself is working fine.
Receive the product on a timely basis. The stickers seem quite durable with a heavy matte vinyl. They went on easy. The accessory light seems to work fine although I don't know how much use it will be. The light does seem to get fairly warm/hot..
What I think would have been more useful than light would be to provide a pair of tweezers to help lay down the stickers (I was lucky enough to have a pair to use -- I highly suggest using a pair.) Clean off your keys well with alcohol before you apply the stickers. I don't think reapplying them will be a good idea, so try to get the positioning right on the first shot.
I see I'll return in 2 or 3 months to report on their durability
-- 4/4/2019, five+ months in and these key stickers have held up beautifully. I use my keyboard for work extensively every day -- these look as good as the first day i put them on. I would highly recommend this product
-- 8/19/2019 -- nine+ months: had a few keys loose their glue due to frequent use (F, J & R) -- a little DAP All-Purpose Adhesive Sealant took care of issue.. This seems like a good fix going forward if any other becomes unglued.
