The VandyVape Building Mat is a good medium size building mat. Comparing with my larger Coil-Master building mat I like the smaller footprint of this mat. Although I like my Coil-Master mat it is the size of a desk top and can only be used in limited spaces. But the Vandy Vape mat having a footprint two thirds the size of the Coil-Master mat gives you flexibility as it allows you to use it without dedicating a permanent place for it, so you can use it and put it away if you like. I like it so much I bought 2, as I took the second one and built a portable wood surface for it, then built in my drill and swivel stand along with a pully wire feed system for a custom coil building station. Although it looks good it also works well with my Avidartisan Daedalus Clapton Wire DIY Tool as well. Even the jig of that tool slides along the surface with no problem. So not only do I have 2 areas to build RTA’s and RDA’s on I have one classy coil building station and these mats give them class. So whatever your building you need to have one of these mats. You never know when a grub screw is going to fall and try to roll away. Just these mats alone will stop the bounce that always send them flying. Not to mention when cutting wire you now have a mat that will hold it where you want. When done just wipe it off as the juice will not stain it like it will wood.
