Personal opinion: Galaxies MTL RTA is one of the greatest tanks available in the market so far.It's very easy to build on have 2 independent airflow wheels that can customize all of the different MTL lovers needs and styles,throat hit is better than every MTL RTA that I ever encountered in my list of more than 40 different tanks so far the best flavor ever in MTL tank is from galaxies mtl rta high end ones fade in terms of throat hit and taste and I wonder why the heck I gave more than 1000$ for those that are very hyped by promoters and reviewers and give placebo effects of flavor because of words and overhyped reviews.So If you are new to vaping or advanced user of mtl tanks and really want a cigarette alike draw I can't really recommend you anything except this tank. Cons: Stiff airflow wheels. Whistling at the smallest airflow holes. P.S.Greetings from Bulgaria.
