Review on 🏃 Renewed Garmin Fenix 5X Sapphire - Slate Gray with Black Band: Top Performance at an Unbeatable Price! by Jermaine Krishnamoorthy

Big, yes, but great for running and working out. I ordered the sapphire version and it didn't come with the second strap you get when you order a new one so it was quite disappointing... The sleep tracker is useless so you could change the setting to not even use it to display . in the appendix. It can't tell if you're awake until you get out of bed. As I sit here updating this review he thinks I'm still asleep even though I've been gone for an hour. This then skews the recovery statistics. Also, if you do a "running" workout and have areas where you walk, your readings will be wrong. This will randomly lower your cadence to zero, which disables the averages. I contacted Garmin support and their response was only because I was running and shouldn't be running. The altimeter/elevation is almost always wrong by 75-100 feet unless you manually calibrate it daily. The need to calibrate an altimeter often renders it unusable. Update October 31st: I rode 9 miles and for the first three miles my heart rate was tracked below 70 bpm. This will reset my average heart rate readings, calories burned and all training effect data. I have come to the conclusion that almost none of the readings are correct. I'm not sure if it's because it's "Refurbished" but if you try to exchange it Revain will force you to contact the seller directly. Extremely disappointing.
