Well no, I wasn't thinking that at all. I've used nothing but mechs going on 3 years now, and would not use anything else. For most of that time I used clones, and had various issues with them, usually the switches, and then I got Poldiacs and have been happy ever since. The only issue I've had with a Poldi was that I was over-tightening the double screws in the switch, and it took me a while to figure that out, but I did, and all is well now. I'm happy
If you know your battery safety and check the resistance of your builds and make sure you have no shorts you should be fine. The thing with mechs is that your build is your control. If you are okay with that you will enjoy mechs. Just get good batteries and perfect your builds. You will want a 510 voltage checker to keep track of where your battery is at, though you can usually tell from how it's vaping.
You do want the mech with the least voltage drop you can get. I found that the authentics are the best bet for that and there are some very fine authentics out there, but even in that camp you can run into some losers, and there are instances in which the clone is actually better than the authentic. It's rare but it happens.
I wish you all the best with this
