The strap can be an issue and I do not see the people saying they had issues with the strap failing saying they contacted customer service to get a resolution to their problems. It seems to me you did not give 4IIII a chance to resolve the issue your having with the straps. I believe your issues are your fault because you neglected to contact customer service.

I have had 2 straps fail and each time they sent me a brand new unit to replace the failed unit free of charge. Both times they said they would be glad to replace the whole unit with a new one free of charge. They sent it by FedEx and I had a brand new unit in four days.

You should not be complaining about 4iiii when you did not give them an opportunity to resolve the problem you are having with their product,

Had my strap for about a month now. I have both this monitor and strap, and two garmin straps and an hrm-dual. I hate adjusting the garmin strap. They've always been a nightmare. This one is much easier to deal with. I ride on average 12 hours a week over 6 days average and this strap has been used more in the last 30 days than my garmin straps. No issues with quality of the strap. Still fine after tons of washing.

I bought a replacement strap to replace the original strap that was starting to fall apart and now after 10 to 11 months the replacement strap has ripped in half.

I had to staple mine together while I wait for it to be back in stock. Strap is poorly made. My wahoo lasted 5 years and only got replaced when the unit got water in it.

I bought the heartrate monitor which is good and works well, but the strap is garbage, after about 30 times of use it fell apart, I ordered another strap, only because I'm stuck with it. This would be last purchase from this company.
