One of my favorite vape accessories is my Coilmaster 521 Tool Stand. This simple hard plastic tool stand holds everything I need to organize my rebuilding tools right on my desk for easy access whenever I decide to change out cotton or coils. It is relatively inexpensive at around $70 and can be purchased on Amazon. I can't tell you how much simpler it makes your vaping life to have your primary tools right in front of you. It has a cutout for your coil master 521 ohm reader and coil pulse so you can be certain your coil build is where you want it and is firing correctly.
