I recently purchased an ego c twist and I am pretty sure it's a knock off, I've got three others I bought locally and they all look the same and feel the same and operate the same except the one i got from discount vapers, the print of the name and the twist mechanism are completely different as well as the size...
A Knock off is when someone is trying to pass a product off as an original brand.
This is a copy, which is something China does really well.
I list prominently in the description that this is not a JoyE product and it's from Hello, so it is a copy, not a knockoff. There are about 15 different copies out there now, all from different manufacturers.
No offense meant to you at all, I appreciate you as a customer, but you need to read the descriptions of the products that you buy, I say this as advise only, from me you will always get the straight answer, as far as I can and I will never intentionally lead you astray or try to con you but you also have to do your due diligence as well.
again, I mean no offense, I just want to make sure you know this is not a bait and switch of any kind. You might get that from others, but not from me.
