I bought this item when it was heavily discounted (about $12) and it got here very promptly, since I am a Prime member. Every can has small dents. The discounted batch I ordered and recieved appears to consist entirely of factory rejects. They were bought 02/2012 and have a 12/2013 best by date, so not that big of a deal. None of the cans are punctured, just small dents. The contents are currently GTG.  I'd say if you are planning on eating these within a few months to a year or so of purchase, go ahead and do it. If not, I wouldn't trust dented cans beyond their best by date, or even really too far before then.  As for the contents, same as you buy in the store. Wife and kid love them, which is why I bought it.  The price has more than doubled since I got mine. Perhaps I just got a reject buy... Be warned.

My son started eating this when he was around 8 months old; he's now 14 months old and it's one of his favorites. Unfortunately, they don't carry it at the local grocery store (they carry other varieties of Earth's Best; just not this one or his other favorites, Spinach/Potatoes and Spaghetti with Cheese); they do carry it at some of the Whole Foods so I buy them there. I'm so glad to find them on Amazon! I get TIRED of ringing up a gazillion little jars at the store.  We use this as a base and mix in other things - bits of cooked broccoli, small pieces of meat. I've also started adding spices to introduce him to new flavors.
