The strap kept pinging off my wrist. To the point where my screen is now cracked on my garmin vivoactive 4s. I've had this watch for 5 years and never been close to breaking it, within 3 weeks of having the new strap my screen was broke. Very frustrating, I have emailed customer services twice now and no response. Don't bother, spend the extra pennies and buy a real garmin strap. It's going to cost me '? ?120 to get mine fixed plus a new garmin watch strap.
