cloned mods

I took steel wool to the insides of the RDA and to the threads and seems much better...

I was wondering, with the large number of cloned vape hardware on the market what some of you think? Would you, have you, etc. ever used a cloned mod, coil, or even counterfeit juice? As I'm still learning and am only moderately educated on all things vape related I may ask an odd question...
