    Cool concept but...

    Posted by Lane on Jul 09, 2020

    This mtl rta has a cool concept with the gear airflow design. It is a bit gimmicky but it does provide a very nice mtl vape. I did have some leaking but my wicking was probably at fault for that. I will say it does produce some pretty good flavor! The airflow has like 5 different settings all of which do not really change it at all. There is no noticeable difference from what I can tell and if there is...it is very minuscule. Other than that i have no other real complaints. It's a great looking little tank that's easy build and fill with its top fill. Some people may be put off by the pctg tank but it doesn't bother me at all. I would recommend this rta if you are looking for good stealthy mtl tank with great flavor.
