Don't buy one! They're defective!
Funny story:
A friend of mine, Heather, had looked high & low for one & finally found a Wal Mart an hour from her that had one. So, she had the store put it on hold & went to go get it. When she got to the store, it was gone! The store had given it to someone else. My friend was pissed!
She got home & got a call from her neighbor. Neighbor was SO excited because she got one! Guess where she got it? Yep, it was the one on hold for Heather! Think the friend gave it to Heather? Nope!
So, I called my local Wal-Mart & asked if they had any. The lady I talked to said that she had 8 that had sold & they'd all been returned because the sides had blown out.
The one Heather's neighbor had "stolen" from her - it blew out, too! Karma is a beautiful thing. LOL
