My stackmat timer is acting strange.
It cleared its memory twice already (has 12:00 A.M, my times are gone, the date is refreshed to 1-01-06). When I go to time myself, I set my hands, the red light lights up, then just as the green light lights up, it refreshes, and everything lights up (Everything shows 8:88.88 8:88 AM etc) I use it VERY often. Is it simply running out of battery? When can I get those certain batteries?
