I'll start by saying that I love my Shine 2 Swimmer's Edition.

I replaced it with a Shine 2 Swimmer when I discovered that the original Shine was not suutable for swimming after I swam with it

I'm also a very fast swimmer and it takes 2 or 3 days for the algorithm to adjust to my strokes

The Shine 2 Swimmer is an excellent device for me as swimming is my exercise of

Very bad R&D on the strap that hold the device.
