I had that before. Some are good, a few had no glow, some had weak glow. I just use the no glow ones as std o-rings. I would contact them for a refund.
I’ve ordered GITD O-rings from various sellers in china, some glow some don’t,
but even the ones that glow don’t look very nice, lots of dark spots, grainy distribution of glow particles…
I wish there were some really good ones somewhere made with very fine particles of strontium-aluminate…
If you read the reviews you will see that they don’t glow worth a darn. I suggest reading reviews and adjusting your expectations from China accordingly.
Pretty sure they do “glow” under UV light (Black Light). Of course the devil is in the details. Try exposing them to a light around 350-370nm. They should “glow”. Of course this stops once you turn the light off. lol
Fastech likely has the same ones. I bought them and no glow as we expect. But under a black light they did.
I had the same problem and for some, found a solution. Lay the O-rings in full sunlight for a day or so. I found that out by accident. It seems like they need activating or something. Hope this can make them work for you. TL
I want to buy some for the color not for the GITD aspect. Just that DX seems to be the only ones with the orange color in the sizes I want. But is it worth the agony of sending money and then never knowing when or if they will ever arrive.
I used to be a very regular buyer of DX years ago when KD was also very popular, but tried out all the many others and eventually favoured others as time passed. I'd suggest to post a poor review too as it's been a bad experience so others learn of it.
Does anyone have an alternative vendor for colored O-rings? I don’t know if DX is just leaving items that are out of stock on their website to make it look like they have stuff others don’t. But I can’t find orange O-rings or tail cap boots at anyother vendor.
