Example Input: I needed to glue a knife handle onto a hidden tang knife, and at first I tried 5 minute epoxy. It got crooked and I couldn't straighten it and ended up having to yank the blade out at the last minute. I cleaned it all up and looked for 30 minute epoxy. This was the only one I could find, but it works great, you get a ton of glue for the price, the tensile strength is very high, and best of all, you get a lot of time to make adjustments to your work before it gets.
Example Output: 5

Example Input: I had my eye on this caddy tray for quite some time. I love to soak in the tub for a couple hours, and if you do too, this is a must buy! I love this tray! It also looks very nice. The only con for so far is that it leaves gray paint stuck to my tub where the ends sit. I definitely recommend this caddy tray!
Example Output: 4

Example Input: With all of the choices to choose from, what I didn't want was a loud fan motor. This is not the one. This fan motor is so loud, I can hear it outside of the building it is in. LOUD! Unsatisfactory. Too late to exchange. A big fat dirty diaper of disappointment. Lame, weak, loud, heavy, loud, fan motor.
