Expressing disinclination for something isn't "hate". It's a preference, and everyone is entitled to theirs.
The only issue I've seen with KR8's is their lack of battery life, and the fact that they look *too much* like an analog; which is just asking for REAL trouble from REAL haters under certain circumstances.
1.) KR808 batteries are expensive. I can buy 2 - RCR123As for my mod for less than I can buy a single KR808 battery.
2.) KR808 batteries are short-lived. I can vape most of a day on a single set of RCR123As, but the KR808 battery won't even hold out for half an hour of my use. Down-time for charging is irritating and, if I carried enough KR8 batteries to get me through the day, I'd have about $96.00-worth of batteries in my pocket. As it is, I carry a spare set of batteries with me at all times, and that only amounts to a $10.00 investment. I've got an extra $86.00 to spend on atties and niquid...yay!
3.) KR8 batteries are tougher to come by than batteries for BB mods. Should my main and backup batteries for my mod nuke themselves (blowing my leg off, or something), I can stop by any Radio Shack (on my way to the hospital to have my leg sewn back on) and buy a couple new ones that'll work perfectly. Radio Shacks are literally everywhere. KR8 batteries are a little hard to come by, comparatively speaking--never saw one in a Radio Shack, personally-speaking.
4.) Tooting on a KR8 is more likely to get you the "You can't smoke here!" line, than hitting on something that doesn't actually look like an analog. People *may* look at you funny, or grumble that you're smoking when they aren't actually certain if you are or not, or somebody might make a crack about that being a cool-looking ....; but, you won't have some security guard skidding to a stop in front of you, waving his billy club around like Buford T. Pusser, screaming at you about your cigarette being illegal.
Just my preference....tomato/tamahtoe, potato/patahtoe..ad infinitum.
