Example Input: Would have given it no stars if I could. The metal piece connecting the two rings just fell off the first time I put it on. I am size xs/s and I got the belt in small - didn't even need to stretch it to get it on.
Example Output: 1

Example Input: This item has great sound. I wish the base as a little deeper though. When turned up to the max it gets a little distorted, but it is seriously loud! Overall a good purchase...
Example Output: 4

Example Input: Beautiful color! Wonderful fit! No, they're not SUPER-soft--but definitely soft enough. Just like the percale sheets I remember from my youth, they've a 'crisp' finish & don't make me sweat. They might soften the more they're washed, but I love them now, having been washed only once. Amy wrinkles flatten out when put on the breed. And they even fit my mattress pocket!
Example Output:
