Good craftsmanship and brighter than I expected. Also very glad that it’s real tritium, not a knockoff, which is what I was worried about. Most products I find use rare earth metals and require charging but the spectra from this peaks at 528 nm, telling me this is real tritium that is producing beta radio-luminescence, with an electron from Zinc sulfide filling a 3d copper orbital. (Probably some Copper/Aluminum mixture.) Really glad to have found the real thing. It’ll glow for decades.

Pretty cool! Got these as gifts for a couple of my fellow military bros. We’ve used tritium lights at work so it made a good gift for them. They’re brighter than I’d expected. In the dark they’re very easy to spot, but faint when the lights are on. Good machining as well - they look good and feel solid. I’m buying a few more since tritium lights are hard to come by. Most products I see are rare earth metals that require light exposure first, but not these - they are the real deal. Always on with no requirement to be charged up. Awesome product guys.

buyer beware if you order something from this website make sure you double check your credit card because they will add stuff to your order that you did not order. I sent an email to the company and got a response that was rude and less than professional. First off let me start by saying this product is way overpriced for the size and quality. I was informed that the extra rod and three extra glass tubes that ended up on my order form where because their product is not that sturdy and the rods can break and the glass can break easily. Why in the world would I order one extra rod and three extra glass tubes for two keychains where does that make sense? When I brought this to whomever is answering these emails very rudely they gave me zero options on how to remedy it instead try to ridicule me after sending me a screenshot of the order form that they added the one extra rod and three glass tubes too claiming I made the order. It's tiny for the money.
