Review: Mushport Stopwatch Timer - As a serious runner (I have been running for 56 years now), I can attest to the fact that this stopwatch is truly spot-on. The timing numbers are clearly easy to read, and as far as battery life is concerned, I have been using this stopwatch on my runs for several months now and the original battery is still intact. Believe me, if you are looking for a very reliable and fair-priced stopwatch, then you just have to give this one a shot.
Review: Simple to use, just what I wanted. - I use my phone timer for everything- timing cooking, reminders of when to leave, time out breaks, etc. However I wanted to start getting in shape at the local track on hole bringing my 8 year old along and thought trying to beat our persona bests could be motivating. To minimize the distraction of my phone, I wanted a simple timer when he could use. This really worked. As I hoped it is very simple to use. And he immediately started timing how long everyday tasks take. Which is a bonus. So now it’s a tool to help us get in shape and also create lots of entertainment and ability to be more patient during activities since toking them creates a n activity. Seems quality. Was an affordable price. We hang it on a mail by the front door and use it all the time.
