Great controller, cheap switch.

I ended up mounting this to my trailer jack using u-bolts I purchased at my hardware store.  There are 3 mounting holes on each side, and the 3 holes on each side are 1.5" apart from each other, so that gives 3" from the two outer holes.  I could not find a u-bolt that was 1/4" so I used a larger u-bolt which caused me to have to slightly drill out the holes for the u-bolt to work.  I like the Engager controllers because of their LED status light so it gives peace of mind making sure things are working.  What I don't like are the cheap break away switches that they include.  They feel really cheap and are difficult to push the plunger back in compared to the older switches I have used in the past.

Works well with my gamecube, a great replacement for my old controller

This is an excellent controller for the price. The buttons are solid and feel much like console based controllers. The analog sticks are tight enough and the D-Pad is the same as a PS controller. About the only thing I could nitpick on is that the controller casing feels to be of a slightly less quality plastic but much better than a cheap brand controller. No software needed. Works very well with Windows 10 and Raspberry Pi systems (RetroPie, Amibian and Combian 64).

I visited the company's website and apparently they only make wired controllers so far. Would like to get a wireless version of this.

Awesome controller. Great for playing games on my phone, with pretty decent response time. The triggers don't work with everything, but I can't complain too much. That's the software developer's problem.

This is a really good controller. The buttons feel sound and the wire gives plenty of length to cover my room. Mind you it's a small room but still. My only real gripe is that the controller feels super light and kinda cheap. Which is concerning when I had ordered a Xbox 360 controller of this same brand and it feels so much sturdier when you hold it.

Basic controller.  Decent enough.  A button needs some pressure when it's brand new.

Overall the controler feels nice, my only complaints are the triggers feel a little cheap and the joy sticks have a pretty large deadzone.

Awesome little controller. Kind of a pain to get it to connect to my phone. It never seems to automatically connect. But the response is pretty good except for the R2 and L2. You have to push pretty hard for them to register. Having clickable thumbsticks for R3 and L3 would have been a nice feature.

Had the Controller for about a month now.  I use it to turn off and on my equipment for my saltwater tank and it does a very nice of that.  The only reason I gave it 3 stars was because after about 10 days, the number 3 switch light went out and hasn't come back on.  It really isn't worth the hassel of calling and getting a new one and shipping this one back.  I would recommend it to friends but with caution.

I purchased this product for some good, old nostalgic fun to use with my Mac running sixtyforce. For full clarity, this product works with the Mac with no problems in any of the available emulators (project64, mupen, sixtyforce and OpenEmu). I've been playing Super Smash Bros. with this (bought another so my roommate could join in) and it works great.

However. The analog stick is not very responsive. It feels more as if it is on a switch, where you move it left and it triggers left, rather than a gradual increase in movement as seen in other analog controllers. I can't quite remember if this was the case on the original N64 controller, but it is certainly a bit annoying. All of the other buttons work fine, seem to have a good clickyness to them and don't stick or ghost at all.

Build quality. This product is not a Nintendo controller. N64 controllers can take quite a beating, as some of them still work perfectly now, despite being 10 years + old. This controller took a fall from 2.5-3 feet (desk)to the ground and broke the right bumper. Internally, the plastic that holds the spring or rubber bouncing part snapped off and is floating around inside the controller. There is no remedy for this. I understand I dropped it, but there are controllers that can take a beating, and this makes me feel a little less comfortable using my other controller in a vigorous way.

There is a black version without the LEDs (http://www.amazon.com/gp/product/B00647NG54/ref=cm_cr_ryp_prd_ttl_sol_2) that I would recommend over this one. The LEDs are a nice touch, I suppose, but rather than make the controller 'glow', they just become a distracting eye sore of 4 bright blue lights. I feel the same way about Afterglow console accessories, too.

Others suggest buying an adapter that take stye original controllers and puts them on a USB port. I feel that is a bit overkill for a casual gamer who just wants to relive some of their past fun. This controller works just fine for the rest of us.

I'd recommend buying it (it's cheap, works well and looks alright), but definitely baby it. As I said before regarding the LEDs, I'd go with the black version (http://www.amazon.com/gp/product/B00647NG54/ref=cm_cr_ryp_prd_ttl_sol_2) over this one, but if this colour appeals to you, then you won't be disappointed (unless you drop it).

I bought this controller because I find the OEM controller to be very uncomfortable (seems I'm not alone - Hello Sony?). The shadow does feel good; all the buttons and sticks in the right place, the rubberized surface is cool (literally) and feels nice, and it is sized for people who have larger hands than Oompa Loompas. Battery life is on par with the OEM unit and the rumble function worked when I wanted it too, which is barely ever since I don't need to feel like I'm holding a sex toy when playing video games. The only bad thing about this unit is the less-than-excellent materials used to construct it, particularly in regards to the sticks. It took me about 4 months to crack the left stick (I play mostly racing and RPGs) and render it useless. I opened the unit (voided my 'warranty' no doubt) and swapped sticks and already the right stick (now the left stick after the swap) is starting to crack. I'm ordering a new controller now before it becomes completely useless. I concur with others' sentiments regarding after-market PS3 controllers: won't somebody build a good one?

Good cheap wired controller with a few faults.  Generally functional, X and D inputs lets it work with pretty much anything you want.  The mode button to swap analog and D-pad is very nice.

Here are my 3 issues with it
1. The circle D-Pad is pretty obnoxious.  It's meant to mirror the X-box controllers, but it's obnoxious on them too.
2. The analog sticks have a deadzone.  That means if you need to frame-perfect coordinate the stick with a button press you'll need to precisely delay your button press (for instance, in Dark Souls 2 it is well known that this controller will prevent you from using the shield break move).
3. The analog sticks began to break down after moderate use.  The "ball" that the analog stick projects from has a seam through it which began to catch on something on the interior. In addition the padding on the top of the stick began to tear away.

If you want quality you should buy a proper X-box controller.  If you don't want to spend the money this controller will suffice for most uses.

Feels great and durable. I haven't had any issues with it other than the power switch on the back is very stiff and takes a lot of effort to switch. I'm afraid the power switch will wear out prematurely. This is why I knocked it back to four stars. Other than that, great controller. Has all of the standard buttons and features of a modern console controller. I use it with my android device. I don't have a PC with Bluetooth yet so I haven't had a chance to see if it really has issues connecting to Windows.

Bought this controller at Best Buy after going to hell to get a Steelseries 3GC to work with Transistor. Worked like a charm. I already had Microsofts's 360 accessories driver installed, so I can't speak to how it is as a "plug and play" controller, but it works just fine as I have it. Buttons feel pretty good, maybe just a bit short of the quality of the official controller. The size is also nice. Don't really care much about the illumination, but it is like some others have mentioned. Just two lights close to each bumper.

First off, I bought 2 controllers and had a different experience with both of them.

The Advertisement:
The image advertised is not the controller I received, I wouldn't mention this here, but I felt that was important.
I have attached a picture of the controller I actually received.

Quality:
The plastic is cheap and very slippery. The edges are sharp, I have already cut myself while using the controllers.
The controllers are light, the sticks are tight, and the buttons are hard to press (that rhyme wasn't intentional).

Performance:
The first controller worked perfectly, the buttons took a bit of force to push down at first but after a few minutes they eased up.
The first controllers' stick seems to be missing its rubber top, but that wasn't really a big deal to me.

The second controller did not work so perfectly, the buttons did not respond at first, it took several minutes for them to even show any sign that they were wired properly. To specify the buttons weren't sticky or anything, I pressed them down, but they just didn't work. Eventually they did work (thankfully), but not right away.
The stick looks a little nicer on the second controller, it has its rubber top and it feels as tight as the other controller.

Both controllers' sticks work well enough and are tight, but I am not sure how well they will work after some time, so I will update this after I have more time to use the controllers. Also, the sticks are in a octagonal shape, so they aren't good for games like Diddy Kong Racing. But for normal games like Super Smash Bros and Mario Party the sticks will work fine.

Buy Or Not to Buy:
Honestly I don't mind the controllers being made cheap or anything like that. To me it comes down to how the stick lasts, if I can save money in the long-run because I don't have to buy "new" tight sticked controllers every few months than this is perfectly fine for me. But if these sticks wear out over time, I would definitely look elsewhere. The sharp edges, I will probably smooth myself. The less-than-perfect response of the buttons, I will probably fix that myself. But for those who don't know how to do that, I would definitely say look somewhere else.

Great telescopic controller. Cheaper and better than the Bounbay brand gamepad (and no dog print thumbsticks).

Thumbsticks are L3 R3 buttons as well, ABXY light up colorfully.

My only issue is the D pad being a bit soft ( not bad though) and the R and L triggers being clicky but weak (so they feel a bit worn). Nothing big, still nicer than the majority of gamepads on Amazon, and I'm addicted to buying and trying new products.

Fits perfectly on my Samsung S8+

Great controller,  only good for fighting games though so it's only used every so often.
