I'm in total agreement, it really delivers and the quality's top notch in it's construction.
I'd be very interested in a comparison with the authentic by @Rob Fisher .
I haven't tested one yet...I have bought a few to test but mates have wanted them so I gave them away... I will get around to it sometime...
I had a go with one but dry burning the coil burnt the airflow insert and I got annoyed and gave up on it.
