Has anyone gone from a 5X to a 5 plus yet. I have had my 5X since it was released and have been very happy with it but being a little smaller could be a good thing.
Don't think pulse oximeter will be any good for me and I take a small battery pack when doing ultras.
I have ordered both and they are still sat in the box and now I have sold my 5X its make my mind up time.
