The ease to use is amazing! I have been using this program for years now, it's easy to set up your account and you can easily see how much money you are saving each month as well as which options you should be taking advantage of. It has never failed me so far but when it does fail, they do send out emails notifying you that there is an issue and what needs to happen to fix it. If you want to start investing or if you already invest then go ahead and give them a try. You will love their customer service and support team. We were able to save thousands of dollars per year by switching our retirement accounts from traditional banks into sharebuilder401k. This helped us build more confidence in our future since we knew where our money would end up instead of being stuck at a bank.
