Review: Really, really awful. The sheer paucity of Alan Dean Foster's imagination is staggering. "Midworld" was recommended to me by a friend; at first I thought I was the victim of a bad joke. Could be used as a blueprint on how not to write a novel. Witless, humorless, and lacking in even the slightest glimmer of originality. Don't waste your time.

Review: The costume was perfect for my daughter and the best part is the costume came with every thing you need to be a very adorable batgirl. The quality was good as well.

Review: It was a great mattress topper while it lasted. However, in less than five years of ownership I noticed the topper lost a considerable amount of firmness. It became too soft to sleep on except for the edges and I found myself waking up less refreshed. It's like trying to sleep on a 'V' shaped mattress.I contacted the manufacturer, Foamex, twice via email but they never responded. Finally I called and was told they won't service the mattress; redirecting me back to the seller who has since gone out of business. I have no experience with this seller, however I would suggest anyone considering purchasing a Sensus brand viscoelastic mattress or topper be aware that you will likely have problems before the ten-year warranty has expired. Plus, even if you find a seller who doesn't turn a warranty claim into a hassle, you will find they are rather expensive to repackage and ship. I will not purchase another Sensus or Reflex brand product.
