Isotope S323 - Stainless Steel Lantern Design Housing for 3 mm x 23 mm Glass Tritium Vial (Not Included) - Everyday Carry Tritium Keychain Accessory - Cool Keychains Accessories

My friend fob arriving missing the ring but I contacted the company and they are sending a replacement. The people at Tec Accessories are fantastic.

Fit and finish are fantastic. Holds a 3x22.5mm vial perfectly. Mine also shipped with two rings and three small rubber plugs to ensure the vial does not float freely back and forth within the fob. I only needed to use one of the rubber plugs (and one ring, obviously), but I am a big fan of vendors who provide extra components.I have dropped my keys and the vial has been fine. I also don't see how the fob would flex very easily, but granted, it's not a solid cylinder wall due to the cutouts, so I suppose with force it would flex. I just don't subject my keys to that much abuse. ;)In general, I am extremely satisfied with every aspect of this product except its price. $19.99 seems to be the point beyond which this seems fairly pricey, especially when one considers you also need to drop $20 on a vial. Oh well, you can pay less for lesser quality. I decided not to cheap out.BTW, with regards to the vials, green is definitely the brightest, but don't believe claims of "daylight bright". Not given the size of the vial. I have purchased green vials from multiple sources and their brightness is all about the same, which is a pleasant glow in darker lighting conditions.

Missing the split ring. Otherwise, as advertised.

This tiny little keyfob is well made and very durable. It does an excellent job protecting the vial held inside it. I'm pretty rough with my keys, tossing them on tables, dropping them, swinging them around in my hand--even though all that, this fob protects the vial inside just fine. And it looks nice to boot.This fob takes a 3mm x 22.5mm vial, and the fit is perfect. Note that the fob comes with two rubber pads plus a keyring. The two rubber pads do not mean you get one extra! Use both by placing one in the bottom of the fob before you insert your vial, then use either the vial itself or something like a coffee stirring rod to push the rubber piece down. Insert your fob, then squeeze in the second rubber pad and push it down. There will be enough clearance between the keyring hole and the top of the rubber pad for the keyring to go in on top of the pad, keeping everything in place unless you remove the keyring.If you need to remove anything, you'll need to remove the ring, then use a very fine tool to push up from the bottom on the bottom rubber pad. This will force all the bits up and out.12/30/2015 Edit: 6 months and still good as new. Durable little thing.

Looks cool and has a great finish, but this thing is NOT strong or sturdy--it bends very easily, and my vial broke within a few weeks. I kept mine on a keychain in my pocket and in a bag, but nothing extreme or abusive. It bends VERY easily with very little pressure, even from your hands. Unfortunately it is of poor quality, and when you pay what they're asking for for such a tiny piece, you expect it not to break the vial it claims to protect. Really disappointed. Avoid if you want to actually take this anywhere.

There's nothing wrong with this. Nothing at all. I give it three stars because:1) Price!!! Who cares if it's titanium or robidium or whatever. It's a tiny mass of metal intended to hold a tritium vial which, as far as I can tell, *isn't illegal*. They're hard to buy source within the USA. I source from Taiwan and am very happy. But, TEC, WTF?2) TEC: WTF??? Yeah, it's cool! I dig it! But $20+ and no tritium and no prime? What an I paying for? I work for a very small company, as yourslikely is, so I understand that side... but $20+ for--and you know this is not paraphrasing, but the same meat as your description--"it's made of this badass metal; there's not much of it but it's super light and strong... you could forget it's there! But you're on your own to find something good to jam in it so that it actually does something, like create self-sustaining illumination as the ad indicates"--WTF, dudes? I dig your s***, have and will continue to buy it... but there's a screw loose: maybe you're a startup doing unique things that I don't understand (... so do a fouling press release!), or maybe you're complacent and--this isn't bad by itself, or at all given your non-public structure and data--you just like guys like me who like outfits like you. I don't like your pricing, but your style sort of normalizes things, so I dig it.I just don't get it. Maybe I'll make a company that makes similar products at half the price... that tiny volume of metal... titanium is just cool. Its core physical properties which make it desirable coupled with the relative increased price per unit (or loss per consumer per buy) thereof compared to, say, steel (which, to whomever may not know, is a medicine of mostly iron and then some carbon, the specific properties of each being tweaked per buy) is a mystery to me. I'll give you this: titanium is cool. But if you used stainless, what would you not deliver to your customer given your costs would be much less, so even halving you price would increase your margin significantly, perhaps by an order of magnitude?Help a brother out. I love your s*** and I gift it too. But what's with the materials and pricing?

This is the 2nd one I purchased. I enjoyed the first one immensely, but unfortunately I lost it. Combined with the tritium Isotope, it makes a great addition to your keychain and helps locating your keys in low light environments. The tritium glows for a long time (years) and the holder is made of sturdy steel to protect the glass Isotope insert (which you much purchase separately). High recommendation for material quality, value for the money and fast shipping time.

Nice product. Solid. It will protect the 22.5mm tritium tube on order.
