One of the most often asked question about Fitbit trackers -

Is a Fitbit Waterproof?

All Fitbit trackers are water-resistant, which means they are rain-proof and splash-proof and can stand up to even the sweatiest workout.

Do not swim with your tracker. We also don’t recommend showering with your tracker; though a little water won’t hurt the device, wearing it 24/7 does not give your skin a chance to breathe. Whenever you get your tracker wet, dry it thoroughly before putting it back on.

You can read more about it on Fitbit’s website.

Reviews That Matter

I recently had to buy a gift for my niece’s birthday. Trying to be the best uncle I could be, I decided to buy a toy best suited for her.

Given my lack of Toy knowledge, I did what anyone else in my position would do - do furious online search.

I consider myself an expert in online research. After years of reading, commenting, writing about technical products, I thought this is going to be a done deal in few hours.

How wrong was I?
