I am addicted. Sold my F3 bought a 5 wireless sapphyre, sold and bought a 5s wireless sapphyre, sold to buy Descent Mk1, sold to buy F6 sapphyre titanium, kept and bought the 6X Pro Solar, now have 2 F5s sapphire's to give as Xmas presents. Oh and have an Edge 1030 on my bike? Despite my disappointment with the screws on the Titanium band, I have never had an issue with any of these devices. Now waiting for the Descent Mk2 with all the 6 pro features, and diving.
So in summary 2 x 6s Pro Sapphyre, 1 x 6 Pro Sapphyre, and 1 x 6x Pro Solar. If anyone knows of a rehab clinic please let me know.
