Review title: A waste of money Product review: You're better off using a regular toothbrush to clean your tongue. This thing literally takes 10+ minutes to scrap of 80% of the gunk, while a normal toothbrush only requires 2 minutes to do the job. Save your money.

Review title: If you LIKED this film, DON'T buy this video! Product review: I only gave this VIDEO one star, but I'd give the FILM 4 stars. I really like this film, in spite of some of the implausable ideas like a single person being able to arm our nuclear arsenal. However, this particular video being sold (which I bought and have just now viewed) is MASSACRED! It looks & sounds like someone set up a camcorder in their living room & taped the movie off their TV. The sound is TERRIBLE, the framing cuts off any captions & subtitles, and, to add insult to injury, they CUT OUT the last 10 minutes of the film showing the journey back to the survivors in Antartica -- it ends with the world being destroyed by the nuclear explosions! Shame on whoever did this! Now I have to go try to buy a used Beta machine on eBay so I can watch my old Beta tape of this movie!

Review title: THE SKULL & CROSSBONES SQUADRON VF-17 in World War II Product review: This text is a fitting tribute and memorial to the original personnel of VF-17. It and the associated photographic illustrations, also give us later generations, some insight as to how the F4U Corsair was developed and improved as a warfighting tool in WWII.Well Done!
