I've recently tried a Halo Triton batteries and clearomizers setup, and I'm liking it pretty good so far. I have to use high (all) VG juices, which is why I had to make the switch from ECHO gear, which is otherwise a very good fat automatic battery setup. That is, except for the limited availability of any ECHO cartomizers or clearomizers that work well with high VG juices.
I would still prefer an automatic Triton battery, and maybe Halo will come out with some one day. I hope they do. In the meantime, for people like me who have to use VG juices, the Halo Triton battery and clearomizer combo is a good, generally dependable piece of equipment. No leaks, and so far (after 3 days), no burnt wicks or gunked up coil (unlike with an ECHO clearomizer or cartomizer). Atomizer coil/wick replacement units are very affordably priced from Halo, and Kanger T2 replacements apparently also work as well, when available.
I'll soon be trying out SI's Volt X2 - Mini T3 clearomizers on my short and fat Triton batteries. Just to try them out, as they are fully compatible clearomizers as far as threading, etc. So you are not just limited to using only Halo cartomizers or clearomizers on a Triton battery. You have some options, and they are pretty darn good ones, including 808 threaded cartomizers and mini-clearomizers, as well as other VGO (EGO outside thread, 808 inside thread) cartomizers and clearomizers. That's still not anywhere near as many options as you'd have with 510 and EGO threaded equipment, but I just don't think those batteries are all that much to write home about in my (admittedly) limited experience.
