I got the velocity rda clone by tobeco and have no regrets. for $30 you can't beat it. unique, easy & fun to build on. did I mention clouds? yes sir, and the flavor is top notch. loads of air flow options plus wide bore Delrin tip doesn't get too hot OR you have the option of your preferred 510 attachment. my only grip was that 6 out of the 8 hex screws were stripped. simply rectified by ordering a 4 pack of replacement screws from avid vapor (the real manufacturer) for $3, still not a bad price and totally beats the original price tag of the authentic. the replacements are flathead screws which are better IMO, who needs an extra tools for that ONE device. did I mention the deep deep
juice wells? they are DEEP. I've also noticed longer lifespan of my coils and wicks, this may be my sigelei from mech transition, can't say, but I'm loving both. the price and options of the sigelei + velocity rda = awesome
