“When we initially received these, both my wife and I loved these. I got her the purple while I got the black. Whenever she used hers, you could visibly see the LED light up, but on my black one, you could sometimes see a small blue LED from the button area, but very faint. Mine didn't work most of the time, and we have multiple cartridges. Now the purple one is failing and only works once in a while. Taking even the hardest of drags, it doesn't turn on the vape, nor does holding the button. We have a few other vapes from this site and love those, so at least we're not out of the 510 batteries.”
“Love it. Before we purchased this, my husband would lose his cartridges all the time. Now, it's always right where he needs it :) especially while playing on his Occulus VR headset.”
“This is a good vape product that you don't loose because it can go around your neck I usually loose mine or it gets lost in my blankets or pocketbook but now I do not loose it only thing that happened was at the end where the wire comes out and plugs into where you screw the 510 carriage on seems like the black is pulling back and you can see some of the wires so I have to be careful pulling the vape string. But definately a good buy if the black wire didn't were back and u can see the wires hoping it doesn't pull out and break. Works good besides that battery lasts long time before needed to charge and uses new charger the phones use which is convenient since my other batteries seem to use the older phone chargers or the other screw ones that break as well.”
