Update 10-30-15
Just added a picture of it working on the 4th generation Apple TV.
*****This controller works flawlessly with the new Apple TV 4 generation. It paired with the apple TV in just a few seconds in the Bluetooth setup tab for the Apple TV. I actually think I like navigating the Apple TV with the Controller better in most cases than the new Apple TV touch remote. I am going to try the SteelSeries Nimbus controller too, to try out, but I think I may be getting more of the Mad Catz C.T.R.L.i controllers because of the button layout is just like the Xbox One and because it feels solid in my hands. The Nimbus has both thumb sticks at the bottom of the controller.
***** Works fantastic with my iPhone 6s Plus

---Original Review---
Everything works fantastic with one exception. You have to download the app on your iPhone or iPad before you par it. It did take several attempts to par it before it took but has worked fantastic sense. All of the buttons and sticks work smooth. Fits my iPhone 6+ with a OtterBox Commuter case just perfectly. Just what I was looking for. Also, my nephew purchased the same exact Mad Catz CTRLi controller and has had the same experiences as I have had.

I bought this controller for use with both my iPhone 6 and iPad Air. I decided on this controller because I wanted one that had a clip to hold the iPhone and one that had good ratings according to Afterpad.com.

The controller is well-built and feels nearly the same as an Xbox 360 controller. Like other reviewers have likely mentioned, the d-pad is not good at all. I didn't think this would matter to me much, but it does. The clip for the iPhone works fine, though it would be nice if it could swivel to change the angle of the device. The angle that the clip uses is not a natural angle for my wrists, so they become uncomfortable after prolonged use. The bluetooth works fine though it can be a bit finicky.

The reasons that I chose this controller are that it has L and R triggers, and has the same button arrangement as the Xbox 360 controller. If I hadn't purchased this controller, I would have gotten the Horipad, which has a great d-pad apparently, though it doesn't include a clip to hold the iPhone nor does it have L and R tiggers, only L and R buttons. In retrospect, I should have purchased the Horipad since I don't really play enough FPS games to justify the need for triggers, and my games that use the d-pad are significantly less fun on a controller with a terrible d-pad such as this one. The Horipad doesn't have a clip, though, so I guess that's a big plus for this controller.

Overall, if you want a clip or triggers, this is the only controller you should consider. If you don't care about those, or if you play a lot of games that use the d-pad, skip this one, as the d-pad is really bad.

This will be an initial impressions review of this controller. I just got it a few hours ago and have been testing it on games for my iPad mini. I will update my review as I have more time to get to know it.

First off, the controllers comes fairly well packaged. It's not great but it's good and it gives off a somewhat quality appeal from the start. it comes with an instruction manual, stickers, a phone mount, and of course the controller itself. The controller upon first look is rather generic looking. The glossy finish and the branding just brings to mind every horrible generic controller I have seen in my days of gaming. Other than that it seems like a direct copy of the Xbox controller. In hand it has a good weight but not too heavy. It feels good in the hand despite the glossy finish it doesn't feel cheap.. All the buttons and triggers feel well done and appropriately springy and squishy. The joysticks are a little stiffer than I'm used to coming from PS4 and Xbox One controllers, but they are more than usable.

The controller paired easily with my iPad and took me immediately to the app to download. After installing the app I jumped right into Real Racing 3 to see if I needed to do anything else to set it up. Surprisingly despite the game crashing a few times, the controller was recognized and worked right away. Like I mentioned, the sticks feel a little stiff but they won't be impossible to get used to. Other than that, the controls felt great for the game and it was really nice to see such solid controls work on such a beautiful mobile game.

Next game I tried was Modern Combat 5 which also immediately recognized the controller. I may have to do some tweaking to the controller sensitivity for this game as the joysticks movement was much too slow for the nature of the game and what I am used to for a first person shooter. Regardless of my initial issues with the controls of this game, I am fairly sure they can be tweaked to work well.

The final game I took for a spin was GTA San Andreas. Using the controller on the iPad for this game brought back some fond memories of playing this game years ago. The controls instantly felt familiar and worked great. I saw no lag in controls at all and was really impressed with how well it worked here.

I haven't gotten around to using this on my iPhone 6 yet but I wanted to point out my only realistic gripe with the controller so far. The clip that attaches the phone to the controller requires a screw. I'm glad this controller offers a clip at all compared to something like the Stratus XL from Steelseries which has a much more premium looking controller but lacks a phone clip. However, the clip is somewhat cumbersome because it has to be screwed into the controller in the way that it does. It is really a minor gripe but I would have liked to see a better method to attach and remove the clip or for them to find a way for it to fold nicely into the controller without having to remove it. Nonetheless, the clip actually works pretty well. The phone feels like it is well held in the springy grasp of the clip. It is a bit challenging to get it in with one hand but overall it attaches securely to the controller and your phone.

Time will tell if battery life holds up and just the controller in general, but so far besides the aesthetics, I'm very impressed with the quality and functionality of this controller. I will update this review as I spend more time with it, but for now, at ~$50 price point I can easily recommend this controller to anyone looking for a good iOS controller.

I've been using this controller for a few months now with my iPad 4. It feels pretty much just like an Xbox controller, regarding the feel, button and stick layout, and feeling of sturdiness. The triggers and shoulder buttons work great. More iOS games are adding controller support, and with some of the better ones, combined with this controller, my iPad feels like a mini console. It works great with my iPhone 6 in the phone clip too.

The only thing I slightly dislike about this controller compared to my Xbox controllers, is that the spring tension on the analog sticks is a little too high for my taste, which can make it harder to be accurate in games which require a lot of very fast direction changes, like some shooters. I've seen other people cite the spring tension as a plus though, so that's just a matter of taste.

I also had a great customer service experience with Mad Catz. I lost the phone clip that comes with the controller, I and emailed Mad Catz to ask where I could buy a replacement, since I didn't see one on their website. They emailed back and said they would send me one for free, even though it was my fault I lost it. A few days later it arrived in the mail.
