Each to their own and you are absolutely right to stay in your safety comfort zone.
I haven't heard of a single Pulse safety problem since I've been on POTV, plenty of regulated devices going tits up though.
I've got 4 pulses and 4 Athena mechs, all have great ventilation and simple circuits with fire button locks, I've always kept everything well within the safety parameters and common sense checking your battery condition, and simple visual check of the condition of your mod, always build and test your coils on a regulated device or ohms tester - very little else to do.
Too many variables?
- Only buy trusted batteries, charge and maintain them properly (which is the same for regulated devices)
- Sensible coil building (same with a regulated device) I rarely stray under 0.10 ohms - usually 0.3 to 0.5 sometimes higher using branded wire or premade coils.
- Visual check of the circuit, by their nature the circuits are so simple you can see if there's any potential problem, the only moving part is the fire button making contact to complete the circuit (something you can't do on a regulated device)
- There are no electronics in a mech so less chance of anything failing
I try not to dismiss anything that I haven't tried, help is always on here and I've learned almost everything from experienced users and the 'scary' transition to squonking on a mech mod was far easier than I imagined.
Getting rid of my Pulses as the Athena's have replaced them so if I get bored I might try a Myth Busters experiment to see if I can get one to fail (safely of course)
