Aspire is doing well making these coils. The 1.2 ohm coils don’t perform well, but the 1 ohm are really great. I haven’t tried the 0.6 ohm yet.
The flavor is absolutely amongst the best of the coils I have used, and the output is enough for mouth to lung and full lung, depending on the air flow. It does get a bit messy changing out the coils due to the design, but with a couple paper towels, it isn't too bad. The only flaw is coil life and consistency. With a full day of moderate vaping (a puff or so every 5 minutes as a testing gauge), generally they will last 5-7 days, with 70/30 juice. However, I've noticed that there is always at least one bad coil in every pack, making them last 2-3 days, with plenty of gurgling and spitting. However, all things considered, this is my favorite pod. I recommend mostly 1.0 coils for moderate use, 1.2 for light hits with great flavor and coil life, and 0.6 for harder hits but less flavor and less coil life.
