5. Dos Equis Box Mod
The Dos Equis box screams quality from the second you lay your eyes on it. The black and Tiffany blue (linked below) begs to be taken home. The Delrin and Aluminum construction feels solid in your hand, all the connections are silver coated copper.
The first I have seen with a floating 510 connection plate beneath a 510 threads but it works flawlessly. The box is tiny compared to some of its counterparts on this list and hits just as hard.
