Dear potential sucker,My first airbed by intex sprung a leak in about a week, so I obtained a refund. I bought this model next, and it lasted almost twice as long!I am now on my third. I should have learned my lesson, but my current intex airbed has been around for about one year, and currently has 9, count 'em, NINE leaks. Everytime I patch one, another springs.Intex also makes inflateable boats. They must get sued for a lot of drownings. No wonder they have no email contact. If you buy ANY intex airbed, you are buying utter garbage.Sincerely,SidWa State

From a woman who sold out her body ages ago and now attempts to be a partisan hack, and poorly at that. Why anyone would want to wipe their feet on this dirty carpet is beyond me. Not worth the time it took to phone in sex.

I have been using my zen xtra for 3 months now and i am very pleased with it. I can drag and drop songs with the nomad explorer. I can listen to it for 15hrs at a time before it needs a recharge and it holds my whole collection of cds.There are however a few cons to this product.The plastic clip that comes on the carring case snaped so I replaced it with a nylon strap I sewed onto the back of the case and havn't had a problem since.There are two things that could really improve this product, a line out and a fm transmiter to use to play in cars that have only a cd player.This is an awsome mp3 player and well worth the money.

Positive
