If you can't cancel your order just sell it all to your mate as he/she seems to know quality gear, TBH if you want to go down the mech route try out a friends first providing they are experienced to see if you like it as a lot of new people don't. If you do like it and understand the safety then look at getting one from a trusted UK seller like KHV or Boldvape if you want to get a clone. My advice would be forget buying cheap clones and look at something like the new Rx mech by Wismec once you have read up learnt and feel comfortable using a mechanical mod
