I hate to be one those who finds faults with new products but I'd like to put my mind at rest... My Apple Watch Nike plus arrived this morning and I noticed a very slight wiggle in the band mechanism. It's not loose by any stretch but there is movement. I'm conscious that if it's not be be moving at all that it could get worse over time. Of course if this is normal then I'll be fine with it. Thanks for any help, this is my first AW s im abit paranoid.
