THIS AIR BED IS GREAT! I HAD PREVIOUSLY PAID WAY MORE FOR THE "A--O" BRAND, BUT THIS ONE IS EVERY BIT AS GOOD AS THE MORE EXPENSIVE ONE. I AM A GAL WITH A "MATURE" FIGURE, AND IT (TWIN) ONLY LOST A LITTLE AIR. WITH THE ELECTRIC PUMP, NO WORRIES! JUST A HINT FOR SOME OF YOU WITH BAD KNEES LIKE I HAVE....I PLACED TWO CAMP COTS SIDE BY SIDE AND LAID THE MATTRESS ON TOP. PERFECT FOR THESE TIRED OLD KNESS AND BODY TO GET UP AND OFF OF. KUDOS ON THIS AIR BED!
Positive

Love the show, which for me has held up well: it's obviously dated but still makes me laugh.What didn't make me laugh, though, was the quality of this DVD. The quality of the transfer, it's as though you're still watching it on VHS! It doesn't support surround-sound, even by just repeating the two channels.There are no subtitles in any language, and no special features of any kind!Worse, mine had scratches right out of the plastic! The scene where Jack comes up to the breakfast table in his speedos is all pixelated. Was that true for anybody else?
Negative

My fault that I did not know that this was in tibitian and had subtitles but the content is good and interesting to see in actual clinics and business in Tibet.

Positive
