Review: Batería de calidad
Review: Prompt and Proper - Works great so far. Actually, I was delighted to find it was available given the limited number of options we had to search for another compatible wireless unit for our older system vs. replacing the entire system. This battery answered the question. In giving it five stars I am assuming the battery will still be working a year and two and more from now. The original lasted five.
