Pros: It is good if you have a full Nvidia setup in your house.

Cons: it isn't good for gaming on the computer because it will be added as a mouse. it has to be plugged in all the time just to use it, and you can't use it with other Bluetooth devices other than the Nvidia tablet.

Pros: When it is working it's a fantastic controller and the features are nice. It feels really solid and it feels like it is built well...
Now inside that's a different matter, read on to find out more!

Cons: There is a defect in the design, the ribbon cables are not very secure and in my opinion the reason they redesigned them.
I own 3 of them, one of them kind of works... the other two are completely dead.
Since I bought mine at Best Buy and didn't keep my receipt there is no warranty on them.
I plan on buying one of the new ones, but you can bet I will be treating the receipt like gold and the controller I plan on using it like mad for 3 months and trying to break it. If it survives I will buy more, if it doesn't I will attempt to get a new one and sell the whole device. You can use other controllers for most things but things like Game Streaming really work best with the original controller... Also voice search...
Also since this experience with Nvidia's customer service, the GTX980 will be my last Nvidia GPU, and I won't be putting "Using Nvidia's software" in anymore of my Youtube video's lol

Overall Review: I wouldn't recommend this product to anyone...
IF the updated version is better (I honestly hope it is, since it will cost me another 60 dollars to find out...)

Pros: Nothing really, read the cons and you'll understand why.

Cons: I don't know if I'm the unlucky one who got one that had a manufacturing defect or if it is the contoller in general but I doubt it.
The controller isn't very responsive, I kept it anyway, but now, it's just as worse as before.
Most of the buttons are unresponsive.
The controller itself, if it would be working the way it should be working, would be a fine controller I guess, but In the end, If I were, you, I'd just get a 360 controller, it's responsive, and it's good, it works well and it's comfortable, I do not like Microsoft much but their controllers generally good.
The Nvidia Tablet is good though, it's nothing perfect, but it has a great video card, didn't had too many problems with it unlike with the controller.

Overall Review: If I could, I'd get a refund, but I guess it's too late now.

Pros: Sturdy, long battery iife. Feels "right" in your hands. onboard mic with google search is great.

Cons: The only con is that the sound crackles a bit when you use headphones with the controler.

Overall Review: The shield tablet is incomplete without this item.

Pros: -very comfortable
-not heavy
-easy to use
-volume controls/headphone jack on controller are very handy.
-battery lasts long
-has a premium feel
-has touch pad/ cursor (useful if you don't want to navigate with touch and with running

Cons: -some games require the use of the soft keys which sometimes results in unintended mishaps in game. (not really a controller issue)
-battery is not user replaceable
-turning the controller on and off not straight forward.

Overall Review: Having the shield tablet without the controller felt incomplete. If you plan on using for PC gaming or game stream it's much better than a third party controller.

Pros: Works with every game I've tried well, I like the feel in my hands it's very comfortable and feels natural to me and I have bigger hands so it was nice to have something that fit so well.

Cons: The USB cable that comes with it is pretty short. So it's fine if you're at your desk and your PC is right there but if you're trying to stream a game to your TV and you're on your couch you'll want to consider finding a longer USB cable.

Overall Review: Install is also easy, works with Windows 8.1 and 10 with no issues.

Pros: The joystick has a quality feel to it, has a built in mic for doing searches, allows you to use a "cursor" on Android, support for PC (although haven't tried), and automatically turns itself off. Oh, and amazing battery life!

Cons: I took an egg off since the manual says you can press and hold the logo button for 5 seconds or so to power it off, but I have only been able to do this once out of 50 tries. It also wasn't clear that the device won't update it's firmware unless it has enough of a battery charge to not power off and brick it, although I suppose this can be a good thing!

Overall Review: It's a pretty darn nice joystick, although since we use Google Nexus players around the house here and was considering getting an Nvidia version of of the player which already comes with one of these, I probably should have held off buying this controller as I will have 2 of them when I do get the Nvidia player. Although having 2 controllers maybe isn't so bad!

Pros: If you like the Xbox 360 controller, this will be right up your alley. It is very well designed though may be handful for people with small hands.

Cons: The volume "button" is extremely sensitive. I hit it by accident all the time.

Cant wake the tablet with the controller (not really the controllers fault I suppose), get on it nVidia

Overall Review: Pretty much required for you shield tablet if you want to game on it (if you don't, why did you buy a shield tablet?)
