The Xoss sounds good for the money. I have to admit I like Garmin stuff and have had good results from them - although I know others have had different experiences. I bought my 705 in 2008 and it's still working. I decided to retire it last year for a number of reasons: the waterproof cover over the USB port had broken, the old Garmin mount isn't great, it's large and relatively heavy, takes a while to lock in the GPS coordinates (although faster than Xoss by the sound of it) and has to be plugged in to a computer to download. The 320 Plus locks in GPS almost instantly. It has the same size screen in a much smaller unit, much the same battery life and downloads over BT.

I also have a Garmin Virb X camera which I've been very happy with. I did have a Vivosmart HR+ fitness tracker which, although it worked very well, I found too chunky on my wrist so I now have a Galaxy Watch. The watch is an excellent unit but I don't like Samsung's Health app as much as the Garmin one and there is no access via the web which is a real PITA. So when this dies I'll probably think about going back to Garmin.
