[EX Q]: Wearing everyday and overnight, this band is holding up great!!! The matte finish has rubbed off a bit and is now shiny, but the band looks and feels brand new. Many compliments. Would buy again.
[EX A]: positive

[EX Q]: This is the second power bank I bought in past two month. The first one turns out the capacity is too big to travel by air. I got this one under 10000mAh. Tested a couple of times. Works great. Built in cables very convenient. Comes with a storage pouch good for travel.
[EX A]: positive
