Fitness tracking wristbands

Anybody use one?
I quite fancy having one....its a gadget after all lol
Can't decide which might be best,Jawbone up24,Fitbit charge hr etc. they seem to get mixed reviews.
For info I train with weights in the mornings and cycle when I can. I have an active job(upholstery).
Waste of money or a bit of (useful) fun?

I was wondering how they work when it comes to moving arms,say ironing,as opposed to actually walking. I was thinking the HR versions might be able to distinguish between things a bit better but not sure.
Incidentally motivation isn't a problem...I just like gadgets and info.
