Great power long running time.

[This review was collected as part of a promotion.] I bought this a couple of weeks ago and it's a switch from the original batteries to the white lithium ones. There is a difference at night and day. This thing runs forever and it doesn't have any drop off until it needs to be charged. I love it.
