Input: Consider Input: I have a smallish black dog that disappears into shadows and night an this collar is perfect to help keep an eye on him. He is so small I was able to get two equal lengths out of the collar portion and I love that it is rechargeable.

Output: positive

Input: Consider Input: There are supposed to be 6 plates and I only received 4! No yellow or purple, the very damn colors I bought these for! I'm disgusted and can only hope this review gets them to send me A WHOLE NEW SET. These are FAR too costly to just get 4!

Output: negative

Input: Consider Input: Very frustrated with this product. It had high reviews which lead me to purchase this glue gun. Within the first 2 minutes of using it the gun clogged up. So I exchange it for a new one thinking maybe I had a defective gun. NOPE! The 2nd gun was even worse. Clogged up almost immediately. I followed the instructions, so I know it wasn't anything I was doing wrong. If they could fix this issue on the glue gun I would say that this product is amazing, but as it is now it doesn't do what it supposed to.
Output: negative
