    Very nicely made build/burn tab much better than others, even the ones made by coil master. This is a little larger than most other 521 tabs, hence the plus, but it is made very well is extremely durable and has a lot of nice features… holds 2 18650 batteries in the battery bay (and charges them when plugged in with a micro usb); magnetic strip on the backside of the device for holding tools, screws and other items. Very easy to build on and seems to give an accurate reading on resistance for your build. I am very happy with this and would recommend it to others and if something happened to mine I wouldn’t think twice about buying another to replace it.
