I have got to tell you, I absolutely love my Merlin Mini RTA in single coil mode. It's one of the best tanks I've ever used when it comes to flavor chasing, to be honest. The only issue I have with is it the low juice capacity, but I am not a chain vaper anyways so it's not a deal-breaker; I understand that it's a regulation they have to meet, and I can see that many new tanks are coming out with that juice capacity anyway so it doesn't matter. I now only use the OBS and the Merlin, and I'll give the Ammit one last chance with a good rebuild before I retire it.
