I saw an Impact sample which I got to play with. Went to the bathroom in the dark and was pleasantly surprised by the strength of the spotlight. However, the store also ahd a sample of the Incandescent Tec 40 which has the same body as the Impact. The bottom of the plastic body was fractured with a portion of the batteries showing. It seems someone may have screwed the head down too tight when turning it on and bottomed out the batteries to the point of breaking out the bottom of the body on the side opposite the head. When I took the battereis out, there was a thin flat piece of metal battery contact on the bottom but no springs like the Impact's smaller cousin, the Attitude. If the Impact had the springs on the bottom, it may not want to break out the bottom of the body when someone tightens the head too much.
Does anyone know how the circuitry allows for 4 batteries instead of the usual 3?
If the body cracks, is it coverd by the warranty? If so, I may still get one.
