This is definitely a tank I would recommend you buy a clone first, unless you've had one before and know you like it.
I had (a clone admittedly but it was 1 - 1) one for a week and found it to be a flavour free zone unless I raised the coil high, opened both air holes and vaped it RDL (which it was good at) but the two air inlet holes aren't directly under the coil, they are on either side and although they are angled 'to hit the bottom of the coil' I'm not convinced it does. You have three choices of airflow with the clicky adjuster - the small hole, the larger hole or both open for a very loose MTL/RDL vape. Neither position worked for me but if one of the air inlet holes is your preferred MTL vape it may not be a problem.
I gave up on mine in a week despite trying different builds, coil positioning etc and gave it to a mate, who also had the same problems.
Admittedly I did have a clone and that COULD be the problem but I doubt it. I would advise caution before digging deep into your pockets for a real one.
