It looks like they pay 5% up to 5000, and 0.5% on balances above $5k.
But -they charge fees for each transaction where you access your money. $1-2/for debit/credit usage. $2.50 for atm access.
And if you don't add money the right way - there is a fee to add money.
Oh - and don't forget the $5.95 fee to close the account and get a check.
It could work - as long as you are very careful and don't do anything to mess with the $5000 you park there, until it's time to withdraw it.
