Query: Very nice product

I bought this product because I need a CD player with anti-shock shock. I found this one is with enough buffering memory for 40 secs within pretty good price range. But after using it for over a month, the most impressive feature which really amazes me is its power utilization. I use a very normal battery(not named brand), but it seems to me that I do not need to change my battery for a month...This CD player really does not consume the power as much as my old CD player. Highly recommend.
