I'm a fan of Square too. I Signed up for both Square and PayPal Here a couple months ago. Had to go through a bunch of steps with PayPal even though I already have an account. Eventually said they would "get back to me" and never did.
Square was clear and easy. They send the device right away with tracking. Even added my partner on my square account so he could cover the booth if I had to step away.. Not only do they deposit directly into your account the next day, but you don't even have to use the device! if it's lost or damaged, you can still manually enter Credit card info!
love it.
