Fastime 500DM Decimal Minute Stopwatch

I didn't use this product for anything as it didn't work, I returned it and explained what was wrong with it and they sent it back to me and told me that it was in perfect working order suggesting I read the instruction manual, the person that I bought the watch for has used these stopwatches for years and told me (showed me) that it was a faulty item. we even checked the operating video on u-tube and we were doing it correctly....

Exactly what I required, & formed a good relationship with the supplier
