Example Input: I use this glue for craft work, I build rustic wall plaques out of cast iron parts. Absolutely have never had a piece fall off yet. Slow to dry, but worth it in the end.
Example Output: 5

Example Input: Our dog Radar has put so many holes in his Jolly Ball we can't count them. The ball is amazing. It holds its shape even though he compresses it when he bites down and carries it around. Definitely one of the best toy buys we've made.
Example Output: 5

Example Input: With only a couple of swims under my belt, there is a marked improvement in leakage and fogging. Comfortable on my eye socket/face and the goggles come with additional nose pieces. Product is 'hair friendly' and attractive. It took me a while to figure out the straps, but I 'get it now' and like them.
Example Output:
5
