Example Input: Finally a gluten free mix that tastes great! I have used this mix over and over and I have never been disappointed. It works just the way the regular mix works and it has opened up a whole new world for me. I thought I would never be able to find a mix that I like, but this one I love. I am excited about trying all the fun things I can do with it. Even cookies!

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: I really enjoyed the Switch.  It was a lot more carbonated than most sodas and stayed that way until I finished it.  I was also surprised that no sugar was added since it was sweet and had real crisp, tangerine taste.  It was similar to Sunkist pop but it tasted more like real juice.  I enjoyed the taste and if you have the extra money and want a healthier alternative, you might want to give it a try, but it is still 140 calories per can.  So it isn't exactly a diet drink.  And the price for the Switch is about 4 times the cost of most soft drinks so I think it would be out of the range for most people's pockets.
