Example Input: Dried mangoes are my hubby's favorite fruit.  He especially LOVES the Philippine brand.  Some come close, but no cigar.  We have searched high & low to find a brand comparative to these, but there are none.  Having them delivered on a regular basis is great & with free shipping.  No more detective work and disappointment.  He does have to be careful however, because he seems to eat them too fast & runs out short of the next delivery, maybe I will increase my quantity!  Quality is the best.  Delivery on a regular basis was a perfect gift for him.  I am very happy & satisfied.

Example Input: I don't write reviews at all but I'm just going to say that this is a very decent product to buy if you're not looking to spend hundreds of dollars on a mixer, phantom power supply, and pre-amp for XLR mic recording. Because guess what this little thing has it all in one all for a low price! Cop you one!

Example Input: The Milka Naps Mix Gift Box is a fun, unique gift for those tired of Whitman's and the usual American brands. Nothing wrong with Whitman's, but sometimes a change of look and flavor is nice.  As a sampler, it provides only a few of the Milka options. Four flavors are here: noisette, hazelnuts, alpine milk and strawberry. All are delicious, though I don't like strawberry/chocolate (in any candy) personally, and give those away to eager friends. The Naps box are perfect for coffee tables and as a standalone dish at work.  Milka and its famous purple cow, is owned by Kraft, is an eastern European chocolate originally produced in Switzerland and is available in Germany, Austria, Hungary and other nearby countries.  Distribution is still weak in the United States, but can be found increasingly in larger cities. Usually, then, it is found only in international grocery stores, though it pops up in eclectic grocers from time to time. It has been around 100 years. Whether or not Kraft will change the recipe has yet to be seen. For now, the texture and taste are better than Hershey's and Nestle. It is a smoother, creamier basic chocolate.  I fully recommend the Milka Naps Mix Gift Box.  Anthony Trendl editor, HungarianBookstore.com
