I found these cheap mech mods on a site called vaporbreak.com. They were 20$ or less. Anyone have any experience using one of these 12-20$ mods? If mods have no wiring then why are some priced so high? Im not new to vaping but I am to mods. I wanna get one as a back up, but I don't wanna spend an arm and a leg. Any advice is appreciated.

I have never purchased anything from Vaporbreak, even though I know of several who have. If you are going go the China route, I would recommend Focalecig or Fasttech, both of whom are closed right now

... And yes, it is possible to get a quality mechanical for a very low price, because they really don't cost that much to manufacture in the first place.
There are a handful of trustworthy, and reputable vendors on Ebay as well (re-sellers of low cost Chinese Mods), they are more expensive than China, but sometimes cheaper than other US online vendors ... just remember to check Feedback scores before you buy.
Whatever you choose, and whoever you decide to buy from, make sure that there have been favorable reviews for both the product and the vendor. You can find some amazing, good quality items for low cost in China, but you can also find some things that are not worth the packaging it was sent it.... Reviews, and recommendations. ;-)
