I have only used my new T 18 a couple of times in the last month working on set building at my local community theater. It seems to me that my 10 year old Dewalt18 v has more power to drive screws into old, hard 2x4 s. The T 18 is set to maximum and is set on the screw icon. Am I missing something? Is this just how the T 18 performs or maybe I have a poor unit that could be repaired. I just checked and it seems that tomorrow is day 31. [sad]
