Example Input: When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
Example Output: Good Review

Example Input: This product seems to be very high quality and I am happy with the purchase. But it is bigger than a regular mug size. The cover makes you go around in circles just as much on your car windows if that helps any? :)
Example Output: Good Review

Example Input: I have a very small head so I was really glad to find something adjustable as my husband is getting bald patches on scalp which don't affect his hair. However, it did not fit snugly like one would expect of the &#34;Flexcare Men's Scalp Support. The top comes past where you are supposed to, and in trying it both ways, there just aren't enough holes for proper compression across that area.
Example Output:
Bad review
