TEC Accessories TEC-SCR Isotope Chain Reaction Fob (Aqua) - Glow in The Dark tritium Vial housing for 3x11mm

Being a Special Operations soldier for the last 29 years in the US Army, I have used all forms of glow in the dark tapes, powders, fobs ect. A few of my soldiers purchased this item and I was able to see how well it performed first hand. As far as the glow fob itself. It’s very robust and holds the tritium very securely. The glow in the dark isotope holds its glow very well, a lot longer than many of the items we currently use today. It is NOT bright enough to read by nor navigate by, but is very useful for locating objects in dark environments. The darker and the longer you stay in the dark area, away from light, the easier it is to see the fob. We navigate many times in complete darkness, so preserving our nighttime vision is critical to our training as well as missions, that being said, we do not use white light at night. I now have this fob, as well as a few others with my gear ready for my next deployment. I will try and write back as to how well they hold up under these type conditions, but so far they have survived over 40 free fall parachute jumps, at least 20 deep water military scuba dives and several months of very harsh desert and urban training scenarios. I just ordered this one in the aqua color to see how bright it is compared to the green. In my opinion, this is a very nice product, and no, the company has not offered me a thing to write this.

Fast delivery and great product!

Deceptive product description, product in fact has no tritium tube and the glow is too subtle and short-lived to be useful. My interest in it was solely as a topic of conversation... Not much of a point if it's just a generic glowing keychain. I guess they got me this time. I see no utility in this item, but you might like it. seems durable.

Doesn’t light up, and stay for more than about 15 minutes. Apply a bright light, and yes lights up, but doesn’t last. Regular light, having on a counter, doesn’t light up visibly at all.

I ordered two, one being aqua and one being green. Got something different for the green one, but the aqua one is fairly visible and with a long persistence. It can't be expected to light up a room, but if you leave it dangling out of a pocket as you go about your day, letting it "soak up" the light, it will glow visibly for a good several hours once left in a dark place. I also fitted a tritium tube from Tritium Workshop, and the pellet is probably brighter than the tube for about 3 hours though the pellet can still be seen glowing another 8 hours later across a dark room. That said, if you want to be able to read under it, you will need something electric.
