i know it has the extra bits for pulse ox internally but is the shell or cover the same? im just wondering if it will be prone to cracking as it has on my (and many others) 5X. my 5X has cracks in the sensor cover, its an early build with the poor usb cable connection too. im thinking of moving to the 5X+ if i can rid myself of those 2 issues but i see a thread about it not working with HRM Run straps in here. Its making me think long and hard before i do anything. $850 is not cheap. want to make sure im not forking over more money for the same problems i already have while adding new problems (strap not recording run dynamics)
