I have an IQ2 and IQC and I'd say they're great vapes. The really nice thing with them is their dosage pods, the stainless steel ones are only 0.3g capacity (ceramics are 0.2g and don't heat as nicely, in my experience) but you get 6 in a pack to load up. And the grinder they sell to load the pods is fantastic. You can easily do a sesh, let the unit cool down for like 10 minutes, pop in a fresh pod and maybe battery if needed, and go again. Great system, you just gotta look around for coupons to get the price down.
