As of now I am done buying clones. My first mech mod purchase was the blackhawk panzer clone with a trident rda. Both are ....! Trident V2 clone has all kinds of problems with posts, and the blackhawk threads catch every .......ing time! Not to mention the well known voltage drop. At this point the trident was useless. So I ordered the TOBH Atty. Love it! Well machined piece of art. Works beautifully and easy to build on. Last week a coworker bought a panzer clone with an atomic rda clone (from the same B&M). He gave up on building after 5 days and so he traded me his panzer, atomic rda, sony vtc5, and charger for EVOD starter kit. I made out like a bandit, I thought. The panzer is better than the blackhawk, but the atomic is already broken. I mean BROKEN!!! I don't know how this guy can stay in business selling this garbage. Both RDA's were less than a month old before completely breaking. Even with the broken rda I still made out on top of the trade, but I learned one valuable lesson when it comes to vaping. NEVER BUY A CLONE AGAIN!
