best impact driver

The Best Impact Driver To Use In a lot of my youtube channel videos i use an impact driver to remove splash shields and skid plates but these have so many more uses in the automotive field and its hard spending money on all of them to know what is the best bang for the buck. Ive used several different brands when it comes to the 12 volt and 18 volt models. but for durability and ease of use and a relatively fast charge time for the light batteries. the model i have in particular is the dcf85S2 it is a 12 volt model and has a 1/4 inch quick connect chuck that fits screw bits and any other bit that goes in i use a 1/4 in socket connection that fits in. i use this impact for taking apart intake manifolds, light engine work and interior panel removal and such its honestly and easily one of the most used tools in my collection and i dont know how i did things without it. in my flat rate situation it has increased my productivity by far and it was worth the expense and i now have two one for home and one for work  

this is a youtube video showing the particular model of the impact driver dcf815s2
but they have many different models of impact drivers if you have a need for more power
