I had made a spur of the moment purchase of a e-cig and wasn't fully happy with the result, then i started to look for model reviews. I watched yours, dusty's, leaford's, as well as others. In the end I settled on the Evo and once it arrived from the UK(agonizing wait) I was pleased with that decision.
Each persons choice is a personal one based on what they are looking for. If wasn't for reviewers like you how would we have any idea what was available, or how they differed from one another? After all i think for most of us this is a online purchase.
Personally I think that it is a good thing that a company respects the opinion of a reviewer enough to send them a sample to try.
If I had to purchase all of the equipment that you, and the other reviewers have evaluated there wouldn't be half the information available to those looking for it. Due to this i don't see anything wrong with a objective review from a sample received, and i believe that you do state if the product reviewed was received as a supplier provided sample.
As far as coupon codes go I, and i am sure many others, settle on what they want and then check for a discount code, which I am always grateful to find. Only wish i could find one for the Evo LOL.
Keep up the good work Scott, and all the rest of the great reviewers out there.
