I posted the other day, looking for a replacement top cap for my sentinel. I bought it used and the threads on the connector had been stripped out so that only my atomizers with longer male 510's would catch and thread in. u/macdaddyvapes pointed me to Triangle Vape.

They're a stateside (North Carolina) business that has (among other things) colored replacement sleeves and cap sets for Sentinels. They're listed as blemished, but I got them in today and as far as I can tell the things are perfect. They also have blemished Sentinels, and if they're "blemished" to the same degree as the top caps I got then they're the best deal I've seen, and I wish that I had just gotten one from them rather than buying a used one that I had to fix.

After I placed my order I got an e-mail from the owner making sure that I was aware the stuff I ordered was blemished. I explained my situation and we e-mailed back and fourth for a bit about potential solutions. He seemed like a really good dude and I would totally do business with him again. In fact, I may have to grab a set of black sleeves to match the black caps.
