[Q]: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.
[A]: Positive


[Q]: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.
[A]: Positive


[Q]: I was amazed to find out that this cable was so cheap and would work with my 1080p tv. Much to my surprise, the cable didn't respond too well to my tv and left me with black screens every so often. When I did my reasearch, I realized that not all HDMI cables are the same! If the cable is anywhere from $1 to $40, chances are it won't work well and isn't HDMI-Certified.Doesn't seem strange to only have to spend $1 on a High Definition cable when your tv and sound system probably cost around 3 grand?THERE ARE DIFFERENCES BETWEEN HDMI CABLES! NEVER BUY A CABLE UNLESS IT HAS BANDWITH, SPEED, COLOR, SOUND, AND FREQUENCY RATINGS ON IT! Also remember, the longer the cable the less data makes it out of the other side!Watch videos on Monstercable.com to learn more about which cable is best for you and you tv.
