best/safest box mod?

[slyider1]

I'm looking to buy a box mod this weekend when I get paid, Im interested in the cana dna 30 mod v3 but I hear that it has melting problems or something? Any suggestions or reviews on other box mods or on the cana? Budget has to be 120$ max unfortunately.

Or mods like a cloupor t5!

Get an IPV or Sigelei.
It's a quality chip set and much less likely to have any of the cloupor "quirks"
