Received my Velocity clone from Eciggity last night. I had read about the allen wrench issue with the clone, I checked the mini screwdriver set I have and the 1.5mm hex screwdriver works perfectly.I never use allen keys anyway. Build quality looks great and the o-ring tolerances seem right about where they should be. Can't find anything negative to say about it.
Built a quick nickel coil and I have to say, the design of the posts is brilliant. 26g 14wrap spaced Ni coil (.13Ω) fits very nicely and attached with ease (pic below). The vape though....sorta meh. Without the ability to close off one side of the airflow, the flavor is muted. This RDA really needs to be built using 2 coils. Dual Ni builds are a PITA though, I attempted one but it is just not worth the headache. May give it another go this weekend with 30g Ni.
For the time being, I put a dual .5Ω kanthal build in there and the vape is outstanding. I like a tighter draw so I have the 2 airflow holes just barely open. With them wide open there is a ton of airflow, then if you open the indirect holes, there is just zero resistance.
Highly recommended if you use dual coils, usable with single coils.
