[EX Q]: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.
[EX A]: negative

[EX Q]: Don't waste your money on these. Sound quality is good for the price, but the headband broke within a month. I am extremely careful with my electronics, and barely even used these things... maybe a dozen or so times before the headband broke. Too bad, I thought I finally found a quality pair of BT headphones at a decent price.
[EX A]: negative

[EX Q]: I received so many compliments on this balloon arch! It’s even more stunning in person! It was the perfect backdrop for photos during my baby shower and the different balloons that came with it worked so perfect together. Highly recommend for the price!
[EX A]:
positive
