  • 9/25/2015 Third Time's a Charm

    3 Review Stars By Anon

    Had to have 3 different ones shipped. The customer service was wonderful each time I called with a problem when the first two were shipped and broken in some way. First the start/stop button didn't work. Then, the minute hand would fall off with the second one. Each time they shipped me a new one for free quickly and paid for shipping of the returned. The third one works great and looks like it was packed better this time!

    5 Review Stars By BC

    My friends all have the old pace clock. So by the time I got around to gettin one of my own it was this new version. There 2.5 pounds I saved by being smaller wasn’t worth not including a handle. I had to go to a hardware store and buy one and attach it myself. Otherwise it was just too awkward to carry.

    Good combination of portability and legibility.  Simple to use and setup.  Time will tell regarding durability, but looks nice and sturdy so far!

    5 Review Stars By Robin

    We put it at the "other" end of the pool as everyone can't see the clock on the wall.  The guard chair is in the way!! It's great.

  • 6/7/2017 Good Value for Summer League Team

    4 Review Stars By Stephen

    Our new Summer League swim coach asked if we could get a pace clock so the swimmers could learn to do intervals.  Pace clocks are VERY expensive, but this one was by far the least expensive.  When it arrived the minute hand was not working and I had to take the cover off the face the clock and screw a nut on to the mechanism.  All works well now.  This clock is pretty basic but meets the needs for our team.
