Garmin FR935 best watch and service

As far as wearable devices goes I personally think that accuracy and functionality Garmin is the best. I have a 935 now due to triathlons and the last week I picked up that there are issues with the altimeter, barometer and temperature. I went to Navworld Pretoria (Marcel) and he had a look at it with various diagnostics and diverted me to Garmin HO. I spoke to Ronald over the phone and he said to bring the watch in. I think from my description he knew what was wrong. When I arrived there was already a replacement as I had a long schedule of multi disciplines scheduled over the weekend. He checked and had somebody else checked from the technical department and boom they replaced under warranty. All in 2 days. Awesome service Garmin this what we expect when we buy a watch at +-R9000. Accolades to Ronald and I can't remember the other guy's name. Also to Navworld Pretoria Marcel
