Hello to start off I bought some flavours from totally wicked and started to make my own juice using the totally wicked mixing guide the result was ok but I found some flavours to strong ie mango watermelon banana vanilla and few more. I have found that the ratios on totally wicked are well off they call for 3ml of flavour in an 11ml mix. I decided to try and half this which I have done and the flavours still come through very well what I am trying to say is anybody buying flavours from totally wicked should try the flavours at half the recommended strength first as I have now had to go though all my mixed liquid and adjust noob mistake on mixing I suppose I hope this could help others just starting out on mixing their own
