Innokin and Sigelei seem to have the best build quality out of the stuff coming out from china. Kanger's pretty decent too.
The Kanger Subox is made out of metal(zinc??) with plastic buttons. The buttons feel kinda cheap/toy like. Uses a single 18650 battery
Haven't held any of the new
Innokin stuff. They do have a solid rep for quality and the MVP's are built like tanks. The MVP 3.0, Coolfire 4, and the new Innocell are all built in batteries though.
The
Sigelei 75w. The original Sigelei 150w boxes have a solid rep with barely any chip problems. Hopefully the 75w are the same quality. The 75w version does have temp control and takes a single 18650 battery. WakeandVape should ship to canada just don't buy any juice.
Then there is the
Dicodes 2380T. German engineering for your first born.
I saw some of these at Thunderbird vapes, they'll let you hold them(on broadway across from that burger place). Saw the MVP 3.0, Coolfire 4, Subox and maybe a VaporFlask(pricey dna40, dual 18650) there.
Best deal is the Sigelei 75w. Gives you the option of using the temp coils that some companies are now putting out and is more future proof. Check out some reviews on it. There should be some on the youtubes.
Online prices are lower though.
