The Focal Hana clone and Hana mini clones are manufactured by KGO or KSD.
fasttech has offered the KSD but most of their Hana clones are manufactred by Hotcig.
I have a Cloupor V3 Hana clone that I will vouch for, and it can be found at a decent price at MBV (be sure to use the coupon) while the newest versions are available at elev8vape.
The Focal KSD models have been reviewed in other languages so it's hard to guage how they stack up--they're new to the American market. The Focal crowd here on ECF seemed to think highly of theirs when I asked. They seem to offer higher quality control than the Hotcig clones that are something of a lottery. The advantage of the Cloupor is slightly better build quality and "instant on" instead of the "wait-to-vape" feature where you have to click the fire button to boot up the chip after it goes to sleep.
Most of these clones don't play well with low resistances--you have to build north of 1.5 ohms. They also don't regulate as well when the battery is low or above 25 watts. If you want more reliability and range, I'd say spend a lot more on an
ipv with a yihi chip.
I like the button on those new 35w Focal clones, but you'd be the guinea pig because no one has theirs yet.
I personally would roll the dice on the Focal KSD model--and I've been thinking about the mini. If the "wait to vape" doesn't bother you, give it a shot.
If you want to play it safe, I suggest the Cloupor as MBV and Elev8vape offer excellent customer service.
