[EX Q]: I've had my replacement bands for 3 months and one side has already broken. I didn't hit my fit bit on anything and wasn't messing with the band. Pretty upset I have to buy another set of replacements so soon.
[EX A]: negative

[EX Q]: Bought two of these mattresses for a bunk bed and they are terrible. You can see where the springs are and there is little to nothing separating them from the cover. Description lists 2" of total foam and there can't be more than a half inch. You get what you pay for but the description could atleast be correct.
[EX A]: negative

[EX Q]: They're really good, definitely work for your phone (iPhone 8+ with a glass screen protector), good grip, but work best if it's just cold with no wind as they're fairly thin.
[EX A]:
positive
