Bests & Worsts Reviews from Amazon

I am a hardwood flooring installer and i expect alot of my tools. I use impact drivers when i screw down subfloor. This driver only lasts about 5 minutes on the 1.3 ah batteries. I went out and bought a 3 ah battery which helped considerably. Another problem i have noticed with the driver is heat. If i am using it to screw down a subfloor, it gets so hot that i cant use it any more. The drill has a cheap chuck that is constantly loosening up. This makes it useless to me. Lastly, this kit is $40.00 less at a local retailer. I should have done my research and got the better kit that was the same price as this kit at said retailer. In the end, I sold the kit to one of my employees, and bought a brushless makita set ($120.00 more than this kit). The difference is night and day. The 4ah makita batteries charge in about 40 minutes which is how long it takes to charge the 1.3 ah dewalt batteries.
