Tuga, I have been using the power pulses for about 3 years before Newell started using them. Hang tight on your batteries because you should get 8 years or better with the power pulses.
I was at a Newell ralley in florida and another looked at my power pulesers and tipped off Newell who then started putting them in their coaches. I hope he got a bonus for the tip off to Newell.
