Purchased two M5s & one M6:
One M5 flawless; HR Monitor, Speed Sensor, & Computer Excellent. Stopped using cadence because using 1 battery per week(about $2.50per). Had same issue with cadence on each unit. However quality build, great functionality, and easy set up forced 3 stars! Calorie function does not compute without use of HR monitor. So I conclude that calorie measurement is accurate based at least on heart rate & distance. Calories are my motivator!
The other two units M5 & M6 had cadence issues burning through batteries also. One HR monitor failed. And the computer had issues reading speed on 2 of the 3 units. So had I stopped with purchase of my first M5, would be 5stars. However, because of other issues had to be honest. Computer battery, Speed sensor battery, and HR monitor battery have all worked more than a month and still counting. UPDATE: June 17, 2018...CHANGED FROM 3 to 5STARS. Because realized tire diameter setting was off. And that's what caused issues with speedometer! Wow. Used auto instead of manual setting. HR monitors have operated flawlessly since putting in new batteries. Also cadence is no longer an issue. I also found Sony lithium batteries for 44cents each on amazon v. $2.50ea at local Walmart. This is an excellent unit for rider who's not interested in competing in the tour de france.
