Striiv Fusion Lite

Just curious if anyone knows if the Striiv Fusion is waterproof/resistant or not?

The box says, 

"Water resistant; bath, water, rain, sweat."

But the site says, it's not and it's not recommended to wear while showering or bathing."

Curious if anyone has experience or a legit answer, since the company is clearly contradicting itself.  

 Thanks!
