Example Input: Review: We got these after seeing the Incrediblocks in the FP Catalog.There are little to no pizazz to the blocks. Some have features where you can "spin" them (like the letter Q - Queen) or the W (watermelon seeds that rattle) - but most are just a "look at me" type of a block.With that in mind - yes I like the product. They're blocks. They're meant for stacking, knocking over and banging - which my son loves (he's had these since he was 6 months). They're better than the plain wooden blocks because they're textured, they have objects inside, letters - lots of opportunities to learn letters, colors, objects, descriptions, etc.For now he's stacking, banging and knocking over. It'll be around for a while until he's ready to learn more words, colors, objects, animals. This review isn't profound or eye openings because again - they're just blocks. Keep that in mind when making your purchasing decision. It will not make your child an overnight rocket scientist =)

Example Input: Review: As of this review, the Kindle edition cost $12.99 and the paperback cost $10.88 - or over $2 more expensive for a digital version that actually saves the publisher money. I actually enjoy Dharma Bums, but Penguin should be absolutely ashamed of themselves for this. I wanted to reread this on my Kindle, but Penguin has decided to screw the readers who keep its business afloat. I'll be sure to keep this in mind for future purchases.Also, for those who will bash my review, the cost of the book is an essential to the value proposition of a book. There are constant bad reviews for publishers that break up short story collection and sell them individually for the price of an individual book. This is no different. Penguin wants me to spend nearly $300 for a Kindle and a case so that they can charge me more for books, all while they save money on production costs??? You've got to be joking!

Example Input: Review: I noticed I was very tired and headachy after taking Vitex, but I read that is a common side effect and that it was temporary. After the first week, I only noticed the tiredness increasing. I would feel almost confused at times and just plain strange. When taking it during the day, one time, I completely drove past the shopping center I was going to. I'd go through these spells where I felt very heady, like I was going to pass out. I was only taking 250mg per day. I had high hopes for this as a treatment for PCOS, but I couldn't continue with it. This doesn't seem like a common result, but malaise and confusion are listed among vitex's side effects. Maybe I should have tried vitex fruit which is less potent than vitex extract, but this is something I'm not messing around with any more! Back to progesterone cream!
