Amazon offers the Logitech PowerShell MFi iPhone game controller for $49.99 with free shipping. This controller originally launched late last year with a list price of $100, but was dropped to $70 due to pressure from competitors. Today’s deal is the best price we have ever seen. It features a built-in 1500mAh battery, console-style controls, and a slim design.

9to5Mac spent some time with the PowerShell and found it to be a worthy first entrant into the MFi controller space:

…I generally had a good experience playing games that supported the controller. For casual gamers that don’t have a problem sticking to the supported games, the PowerShell won’t disappoint despite a few shortcomings. If you’re a hardcore gamer that will be playing for hours on end, the buttons on the PowerShell leave a lot to be desired.

Here’s a list of iOS games are are currently compatible with MFi controllers. Amazon reviewers rate it 3.5 out of 5 stars.
