Solid controller, works well.

My kids really like being able to switch the D pad from "cross" mode to full circle.  I guess it matters to them...anyway, the rechargeable battery and the long recharging/play cord is very nice.  It's saving on batteries for me.

I'll keep this short and sweet,
1.  in order to use it as a fully realized gaming controller you have to make sure the mode light is on,  otherwise only half the controller works.  that is not a problem.  as the button is right in the middle and easy to access,  just....in my opinion ...not necessary.
2.  has plenty of buttons for all you're button mashing needs...however the 1-6 buttons are really close together.  so it's very easy to mash more than one,  especially if you're like me and have fat fingers.

other than fore mentioned.  Works as intended.

This is surprisingly one of the most usable third party controllers I've ever seen.  I've used a lot of Mad Catz and Nyko-like junk since Genesis and N64, but this one actually holds up.  The biggest shortcomings are the d-pad and L3/R3 buttons.  The d-pad is a little stiff, but usable.  Still, I wouldn't expect to play Street Fighter or anything on it.  For 2D games I might suggest looking elsewhere.  The L3/R3 buttons are also nearly impossible to click.  It requires too much pressure.

Other than that, this controller is great.  You can't see it in the pic, but the triggers are similar to Xbox 360 triggers and have a very good feel.  The face and shoulder buttons have slightly bigger throws than a Dual Shock 3, but still feel solid.  The analog sticks are a little stiffer than a DS3, but also completely usable.

It's also worth mentioning that this controller is bigger than a dual shock 3.  It fills my hands completely, which I don't really like, but it's a matter of taste.

This controller is near to perfect IMO.
Pros:
-Wonderful DPAD
-Great grip
-light up buttons
-no fancy driver/setup (just plug in and go)
-Nice clickable buttons (not mush, or squishy)
-Extra button

Cons:
-Thumbsticks often make my fingers slip, but nothing too bad.

I've used my share of 3rd party controllers, and it would be an understatement to say I had my doubts about this controller.  So many have lackluster controls, dodgy build, and near compatibility.  Worry not!  This controller delivers on all fronts.

It works, it works well, it feels good when you use it, and I don't feel cheap when I'm using this controller.  Yeah, it's corded, but the cord is a decent length and has a detach feature to keep things safe in a crowded living room.  The sticks feel a little different from the OEM sticks, but they are responsive and don't feel alien.  The buttons feel almost identical to the OEM controllers (I've used a couple 3rd party controllers that couldn't even manage that), and the overall texture is grippy but not "weird".

All this being said, I don't use these as my go to controller.  I have a couple wireless ones, and wireless on the Xbox one works very well.  I use these when they're charging or I need an extra controller.  I also use these on my gaming PC.  These just work with no need for drivers or other issues.  As a Xbox One compatible controller (which itself is basically the same as a 360 controller), most PC games support this rather well.

I was a little skeptical, as I've run into problems with third-party controllers before. I bought this controller largely on a whim, honestly, because I wasn't willing to shell out ~$30 for the Microsoft version, and it had pretty good reviews.

This controller is great. I use it purely for PC, and was worried I'd run into issues with drivers, but did not. It works smoothly with every game I've tried. The controls are not as sensitive as they could be, but definitely get the job done. I cannot speak for how long the controller lasts, but will update if it breaks.

I've owned the controller for just over a month now. I've played roughly 30 hours of Rocket League and about 10 hours of The Witcher 3 with the controller. I have my PC hooked up physically via an HDMI cable to a 42 inch TV in the living room. I previously used a wired X-box 360 controller while sitting on a la-z-boy chair.

Some thoughts:

Pros:
-The dual-stage triggers and grip buttons are a massive improvement compared to a 360 controller
-The right track pad is great for a kind of "mouse-look" in The Witcher 3
-Using it as a desktop mouse for light internet browsing is great (especially the haptic feedback as you roll your left thumb in a circle to scroll)
-A benefit I didn't expect was is how great it is for things like the Windows 10 Plex and Netflix apps
-Big picture mode - which you have to use - is actually pretty slick (as is changing a controller config in-game)
-Not many games have native support but many games do have recommended configurations that you can start with and community configurations that are popular because the cream rises to the top

Cons:
-Expect to tinker with the settings for the first hour or so in any new game (frustrating if you want to just jump right in!)
-I hated it at first because it took me about 5-6 hours to adjust to the position and reduced size of the XABY buttons, but once I got used to it, its fine (not really a con now, but you should expect to feel this when you start using it)

Neutral:
-I haven't seriously used the gyroscope yet, but I can definitely see the potential

In conclusion, once you get over the initial learning curve, it is an excellent controller. It has replaced my x-box 360 controller. I don't have any regrets in purchasing this controller.

Paring up with my devices didn't had any issue. All bottons respond very well, although the analog isn't that sensitive compared with the controllers of a Playstation's, but isn't a big issue that this controller still deserve 5 stars on me.

I happen to like the original XBox controller. I like it much more than the S controller or the PS controllers. This one feels better in hand though, and is great for gameplay. The wireless is less like the crappy ones you fear and more like the greatness of the 360's stock controller. Your headset plugs into the dongle, not the controller, but my original XBox can't go on Live anyway, so I care not. I mostly picked this up for use as a remote in XBMC. The cord was just annoying sometimes. I did not purchase at Amazon, but at Dimple I grabbed a used silver version. The analog sticks and all buttons and triggers are good, but the analog function is a big problem is XBMC. This thing has NO DEAD ZONE! What I mean by dead zone is that any decent controller has a dead zone where it will allow atmospheric pressure to change without registering a button press. I've found that I basically have to start a movie and pop the batteries out before the controller starts to fast forward or skip back out of control.
This product is aptly named, as you must have the precision of a surgeon to use this thing as a controller.
I've read that there exists a revised version of this controller with proper dead zones, but it introduces new flaws as well. I'll go back to my corded controller with a long extension for everything but some emulators, since they let you set a deadzone in the software.

Works well, good range, comfortable for me, and construction seems to be on par with other controllers like the F710 and XBONE controller. I like it better than the F710 actually (I have, and have had issues with the F710), time will tell as they develop around the hardware.

Controller has a great feel with no dead spots.  I like the size and feel better than the DualShock controllers.  Battery life is great.

Synced with the PS3 quickly with no issues.

Also, when plugged into a PC, the controller worked with most of my games I had on Steam.  I didn't try to pair it via bluetooth to my PC.

The only complaint I have is that I can't charge it using my controller charging cradle.

I've been wary of third-party controllers for the longest time. They generally fall short of the quality provided by the first-party standard, sometimes frustratingly so; mushy buttons or triggers, loose analogue sticks and easily broken bodies are to be expected when going with the (usually) cheaper alternative. From my time spent with Power A's Mini Pro Ex for the 360 -- about two-hundred or so hours, I can say that it has been a much more pleasant experience than what I'm familiar with.

A major selling-point to me was the decreased size of the controller; I found it to be a bit more comfortable to hold and play with for extended periods of time. My hands aren't tiny, mind you; nor are they fatigued by long hours of gaming, but the difference was noted. Ergonomics-wise, the Mini Pro is shaped nicely; it doesn't feel alien in the slightest and I didn't spend much time having to get used to the thing. Comparing it to Microsoft's default game pad, the EX is much slimmer and thus isn't as taxing to grip. In terms of length they're nearly identical, and the same goes for weight -- the device has a pleasantly solid feel to it.

Getting to the important bits: the analogue sticks are excellent. They're tight, responsive and produce a satisfying click when pushed in. The same can't be said for the digital pad, unfortunately; while precise enough for switching between items or various other simple functions like menu navigation, I can't recommend it for fighting games.

Moving onward: the face buttons work well but lack tactility; they sink in without either resounding audio cues or physical ones. They're not bad, but they're not particularly good either. The left and right bumpers are the exact opposite, having a nice give to them and responding with a little click. The triggers are a bit weird for me, however: the left is perfectly fine and sinks-in without issue; but, the right has a bit of the before mentioned mushiness to it. It in isn't a fluid motion, and the difference between its counterpart can be distracting. Despite this the trigger still functions, but at the cost of sometimes breaking immersion for me.

Lastly, there's a button on the back of the controller that makes the face-buttons and bumpers glow, for whatever that's worth. There's also a slot for the 360's headset, and the 10-foot cord has a break-away portion to it in case its tripped over.

If anything takes a turn for the worse, I'll be sure to update the review. As it stands, the Power A Mini Pro EX is a less chunky alternative to Microsoft's own wired controller and a less expensive one to the wireless variety. Is it better than those two? No, but Power A has closed the gap between first-party and third-party controllers, at least a little, and that's much more than what I had anticipated.

Dig it. Works well. Nice control. Solidly built.

Simply put, it's a good controller for a good price. I've only had the controller a couple weeks, but it seems to have a solid construction. It works well with Windows 7. Buttons are easy to press and the dpad is good. It's basically just like the old PS2 controllers. The only thing I don't like much is the analog sticks; the case around them is square instead of circular like the Playstation controller. This controller works really well with emulators. Very slight lag, but it's so small that it doesn't take much to get used to.

I love this controller, very nice looking and works perfectly.

This is one of those products, that while far from perfect, stands alone (thus earning that 5th star) at what it does and does it really well.  If you want the best controller for games that support controllers, I'd steer you towards razer's 360 controllers.  If you want something to control PC games that don't support controllers, the Steam Controller is amazing.  The learning curve on customizing things, especially trackpads and the gyro, is steep, but that's offset by a rich community sharing of controller profiles per game.  While learning how to tweak it to your tastes, you can learn by looking at how someone else set it up a particular elements and then replicate those settings manually on a different game.  It's surprisingly easy to hop into the overlay and tweak one thing at a time as you play.

The Steam Controller is a pioneer.  Big companies don't usually do stuff like this because they're afraid of supporting something so complex.  Steam deserves major cred for stepping up and providing a highly polished combination of hardware and software otherwise unavailable.

I cannot vouch for the analog sticks yet as I haven't used them, but the rest of the controller seems to work fine. Pairing is pretty easy. My only real gripe is that it uses the Mini-B USB connector to charge.
