FWIW, I have a Cthulhu Ceto and love it. I'm sure a burnt hit would be awful, but I've never had one. That's one of the major upsides of the big volume of wick. It holds so much juice in reserve that you get plenty of subtle warning of the wick drying. In that respect it performs more like a BF RDTA than an RDA. Much more consistency than your typical RDA.
That said, I've never not found a mesh build I'm really happy with on a mech, even with a 30A continuous battery. Ramping a bit too slow and vapor a bit too cool. So for now the Ceto stays on my Dripbox 160 set at 90W. That's my only negative about Ceto/mesh so far.
