Do not do business with this company.
I've had constant problems with RentZero. Games have been lost. I've waited over a month without a game ...a few times! And they don't respond to my complaints. I've tried to resolve the issues, and I told them I'd be posting comments online. They didn't even respond to that. I feel completely ripped off. I recommend that people avoid doing business with this company - it's bad enough that I put up this web page just to warn you!
I would recommend any of the following alternatives. Please look at online comparison and review sites to find the best option.
