Sony WM-EX570 Walkman review

I've found this style of sony Walkmans that taking one AA battery in front facing like this WM-EX570 very unreliable. The mechanism of transport is rather loud and suffering from fragile idler breakage as it's made of plastic with metal centre. In my opinion they should be avoided but as a collector one in good condition would be a nice addition to anyone's collection. Enjoy.
