I must say, I really like the direction Aspire has taken with their new Revvo Aspire Radial Coil (ARC). This particular coil is similar to the DIY stove-top style coil, only it's made by a machine and cut out of a kanthal disc. The Revvo ARC coil will give you fairly large clouds as well as full and long-lasting flavor!
Even when you get a dry hit (due to forgetting to turn the tank upside-down) your coil is still not completely ruined like most other coils on the market. I've been vaping on the same coil for over a week, at the time of writing this, I've gotten 3 dry hits, yet the coil still survives and remains flavorful.
Each Aspire Radial Coil (ARC) has a large surface area that contributes to the large cloud production and excellent flavor. I am thoroughly impressed by the Aspire Revvo ARC Coil.
