But the ordering process gives no option to select which strap length is required so this order page will give you the small one.
Maybe you’re supposed to get both in the box? I didn’t.
Next gripe is the battery life. Charge it up before going to bed. Wear it through the night to monitor sleep. Out of bed for a 2 hour dog walk before breakfast and it’s whinging about low battery. This is maybe my fault. Switching off wifi and BT etc might make it last longer. Or battery saving mode? Would that switch of location etc. Need to experiment more with that. In any case. default setting runs the battery down very quicky.
Next thing. If you need reading glasses but don’t need to wear glasses when you’re out jogging then you’ll be able to see the time but don’t expect to be able to see any of the fitness detail without your glasses. Larger font makes no difference. It would be nice to see bpm, speed, distance etc without having to out my glasses on. I’m not blind, btw. My readers are just 2.0.
Maybe I’ll find a solution in settings or find a different setup I can download.
Apart from all that. It’s a nice looking watch. Feels well built. I like the rubber strap even though it’s a bit tight. As soon as you get it. Put it on the charger. Plug it into your phone. Answer a few questions and it’s all set.
I’ve only had it 24hrs. I’ll probably come back and add more review.
