AVOID the protection as you will charge for more fees than the bounce check. I setup some auto-pay transactions and transfers online. It's been working great for me until my wife wrote a check and forget to transfer the fund from money market to checking. So the Checking plus pay the check without notifying me along with the $10 fee. Even though I had more than enough fund in the checking account in 2 days to cover the "loan" from checking plus, the system WILL NOT pay back the loan automatically. Instead, they will just take the minimum interest fee AUTOMACTICALLY from my checking account every month. If you are like me who will not go over the monthly statement line by line every month, you will be paying for the interest forever and still own them the original "loan". In my situation, I was paying the interest for 6 whole months for more than $300. Again, when I discovered this, my checking account had more than $5000 balance and I will need to go in and transfer the fund back to checking plus to pay for the loan and stop the interest!
If you have time to keep track of the money and statement, then you will not need the service in the first place and won't get into the trap like I did. Good luck.
