As a Pod Mod the Boost Fracking Rocks. I have 2 of them and its all that I use now. As for the coils they are excellent. The .4 ohm's coils are as flavorful as any RDA that you might use. They Last forever also. I am getting 2500 to 3000 vapes before they start to fail and lose flavor. And the price is really great. A 5 pack for less than $20. If you are looking for a "LIFE PROOF" mod, one that will take all the abuse that you can throw at it and keep on vaping you should try The Aegis BOOST. IT ROCKS ALL DAY LONG.
