## Questions & Answers

**Q: charger cord included?**
A: The charging cord is included, but it may not have the original fitbit charging cord.  It is supposed to come with a charging cord that has a button toward the base so that you can restart it if needed, like if the display goes away.  The cord that I received through Amazon does not have this button, so restarting it is a bit trickier.

**Q: Is this waterproof?  Would it track swimming sessions?**
A: Hi @VladQui, the manual says that the HR function is disabled because the optical HR method doesn't work accurately through water (it's shining a light at your wrist trying to gauge blood flow and water bends the light). That said, if you only want a relative number, I've found that if you manually set the start of a "workout" (the most generic of the built-on choices) as you get into the pool, then it will give you HR data. I also snug the wristband extra tight.  Also, you can set pool length -- on the Inspire HR, open Exercise and choose Swim, then swipe up and tap pool settings.  It will then allow you to set the pool length.

**Q: How accurate is the HR tracking for strength training/weight-lifting workouts?**
A: It’s pretty accurate. I was using this while hooked up to a halter monitor. It was very close.

**Q: Does the screen on the lilac option actually have a purple tint to it?**
A: I put it next to paper, white sheets and and a white napkin and covered the bands.  The images do have a purple tint.  It appears that the whole “watch face” is a purple tinted continuous surface.  So yes, your eyes see real lilac.  There are grey tones and thus some grey dots where the image needs depth or delineation.  So, the majority is light lavender and the remainder is grey.  It’s pretty darn cool and pretty, too.  You will like it. ( my sis has a black band and I also compared face-to-face with hers). Enjoy!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best Activity Tracker
*by S***. on 17 October 2019*

Love the product. Very sleek and easy to wear. Tracks sleep, HR, Exercise pretty well. not the most advanced but enough to keep you motivated. Highly recommend the product.

### ⭐⭐⭐⭐⭐ Quick replacement for defective unit
*by M***I on 10 July 2020*

The first one I ordered had trouble charging, but was replaced swiftly.. The first couple of days have gone well and I’m sure this is a great buy.

### ⭐⭐⭐⭐ Great Product. Would HIGHLY suggest you get a screen protector for it
*by R***R on 31 July 2019*

31 JULY 2019 - I’ve had this device for a week. Here is my honest analysis on the device PROS: •App is easy to use •Detailed sleep readings. •Short recharge time (1hr, 15m) •Subtle call and message notifications. CONS: •Battery life: Although the estimated life is 5 days, I noticed it didn’t last half as long and needed to recharge every 2 days •Screen damage: Within a week I saw a few scratches and the outer screen managed to obtain a small burn. •Hourly steps reminder: You can’t adjust the amount of steps. Maximum 250 My best feature would be the breathing regulator, also known as “Relax”. It really helps you steady your breathing and would be very beneficial for people who struggle with temper management or anxiety. If you’re looking for a watch to start getting active or be more aware of how effective your fitness lifestyle which is affordable and hassle free, this would be the watch for you.
