In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Example Input: This kit pulls together several standard components rather nicely. I am using it for supplemental grazing of horses, particularly to get small areas that are not permanently enclosed as pasture, but that get overgrown and/or delicious.  I like it. Setup time, once you figure out the components, is about 15 minutes. It has all the pieces to make a very reasonable temporary electric corral - tape, posts, charger, ground, and gate hook.  The 8 step-in posts are fairly standard: they have nice pointy metal stakes at the bottom that make them relatively easy to insert in moist ground. You probably can't get them into rock hard dry ground, but that's not a surprise. There are clips to give you flexibility in the fence height. But - you've probably seen them at the feed store - this kind of post is pretty short and will feel quite short compared to a normal horse fence.  The kit is supposed to come with 200' of 1/2" electric tape. Mine (as a Vine kit) only had 100'. This is enough for one very well behaved horse in a 25x25 square. The tape is not much of a visual barrier, especially with only one strand. This is not a fence I'd trust for a problem horse or for long unattended periods. 200' would be enough for either two strands or to have a 50x50 square and would be a much better value of time spent to grazing time. 50 x 50 is still quite small and the fence is still not substantial. It would be straightforward to add tape, but adding distance also increases the load on the charger.  The product description says 4-5 horses. I would not feel safe doing that. Two quiet horses who know each other well and are already familiar with electric fence, maybe three for very brief periods, if you had the 50 x 50 and were nearby or had a secure outer fence. For grazing, three horses would have the area mowed in just a couple of hours.  The charger - which uses 2 D batteries - has plenty of zap new. I was pleased by how easy it was to work with. It has its own spike, allowing you to set it up away from the fence.  The connections are long enough that you can put it out of nose range. The grounding nail was easy to set up and pull out.  I like that it comes with a simple corner bracing system. You can set it up without the corner braces, depending upon how tight you like your fence and how stiff the ground is. But when you need the braces, you're glad to have the option.  The tape comes on a handy small spinning jenny, which is designed to hang on the fence when it is installed. It's a simple thing, and thoughtfully done. It makes it easy to unroll the fence when setting up, and easy to reroll when putting it away. There is no problem doing the whole setup and takedown by yourself.  The hook for the gate isn't quite a match for the brackets on the posts. A little bigger hook, or some sort of metal bracket, would be nice, to give a sense of a more secure latch. Still, you're counting on the fence never being touched, so it's not a big problem.  The bag for the kit is amazing. Everything fits inside beautifully, with thoughtful pockets - even a special pocket for the instructions. It is easy to carry and extremely organized. I was very impressed to see the thought and effort put into the bag, which makes the kit much easier to use and deal with than just a pile of fence parts. The bag is big enough that there is room for extra items in both the long post compartment and the smaller bag section.  This is a very nice and handy kit to have around if you have quiet horses that respect electric fence.

Example Input: Having eaten (and re-eaten) my way though all of the DAS caramel range, this remains my all-time favorite, and the one that usually gets the most rave reviews when I share them (which isn't an easy thing to do - just try one and you'll see what I mean).  I've been a caramel fan for ages, and while Werthers Butterscotch will do in a pinch, nothing has come closer to what my mother used to make than these.  They are chewy, buttery, and the little crunches of salt are spectacular (OK my mother didn't put salt in hers, this is an improvement).

Example Input: Unlike another product I reviewed for Vine, at least this product does not have sugar per se in it. It is carbonated water added to a concentrate mixture of (in this order): apple, grape, tangerine and last - as well as least -- acai concentrate. The first two on the list, apple and grape are two of the most common "fruit" sweeteners used in beverages etc. That is why the product tastes sweetened.  It has 140 calories -- quite a lot for 8 oz of flavored carbonated water -- and all of it is from carbohydrates (36 grams) and over 90% of the carbs (34 grams) are sugars. Apple and grapes have some of the highest concentrations of "fructose" a fruit sugar that not only commonly appears in commercial beverages because it is sweeter than regular cane sugar and thus it is cheaper to use, but it is also known to cause diarrhea, particularly in children.  So another drink on the hit parade of "pretend" healthy drinks- appealing to the masses' concern for their ever-growing girth -- and deluding them that this will help forestall continued growth.  You are better off drinking diet coke. You would be even more better off buying the sparkling flavored waters with no calories. My favorite is Bella Familglia -- in pomegranate, lime, lemon and orange flavors -- and is sold from time to time on Amazon as well as your local supermarket.  Better yet, buy some organic pure fruit juice -- such as pomegranate and pour  1/8 cup in a glass of your favorite sparking water or a quarter cup in a 16 oz bottle of your favorite sparkling water. At least it is the actual juice and not some fructose extract.
