I had done weeks of research on which E rig would be best for my usage and this is King.
If you like doing back to back dabs and don't want to worry about battery life this is the unit for you. I will fire back to back dabs throughout the day working from home.
The only downside I would say about this unit is the price itself, it is pretty expensive BUT this is definitely a product that is worth the tag. That being said all the pros to this unit far outweigh the single con of cost.
The colors are awesome and there are 25 settings for that as well as over 25 temp settings which are all easy to figure out. Plus it comes with little cards under the unit itself that has diagrams and quick tips on things you can do with the unit.
