1. If by putting it in your pocket, it is heavy enough to pull down your pants, don't buy.
2. If it is bulky just to hold more batteries or for no apparent reason, don't buy.
3. If it has a battery door that can easily or accidently opens by itself, don't buy.
4. If it is ugly like a bomb remote controller without an antenna, don't buy.
5. If it requires a computer for fine-tweaking or upgrade firmware to work correctly, don't buy.
6. If its 510 connector is only gummed in its position or lacks threads, don't buy.
7. If it is driven by batteries other than AA or 18650, don't buy.
8. If it is expensive just because it adds color display, don't buy.
If you really want to find a mod without all the above problems, go to the future.
