Main button feels like not very quality

Not very intuitive to operate. Spent much time figuring out the ways to operate it. I have had many different MP 3 players, but this one.... Main button feels like not very quality.

The Good:

Inexpensive, nice feel, the software is easy to use, weight adjustment, lots of LED color options, braided cord(I'm not a big fan of braided, but a lot of people are),

The Bad:

Given so many positive reviews I thought this mouse might be a steal, but 3 days in and one of the arrow buttons has already lost it's springiness.  It still works but feels odd when using it.

I don't find the feet on the mouse to be very slick, at least not on the hard surface Func Industries mouse pad I have.  I also have an old Logitech MX510 with skates which feels like it's on a cushion of air when using it, but this mouse just feels ordinary.  Both are supposedly Teflon but I'm getting much more friction with the Mammoth.

I still think it's worth the 3 stars given the options you get for the price, but given the quality, you might want to look elsewhere if you want something to last longer than the warranty does.

While the controller buttons function similarly to the original NGC controller pushing buttons feels very rigid and forced. There is very little smooth transition between held and released. The controller also has a faint smell of paint, making it seems as thought the paint job on the controller was rushed and not polished as meticulously as the original.

Looks great, feels great. However compared to the official microsoft branded controller the buttons are much less responsive, typically making it so i have to press it harder than i should. Thumbsticks also feel a bit stiff. Spend the extra 10$ and get an official.

I have no problems with the small buttons and the camera is fine. Looks nice. When I want to make a call or send a text however, I can't just scroll down through contacts. I have to go through several menu items to get to where I need to go. My old 2 to 3 step process has turned into a 6-7 button pushing experience just to send one test. Also, some callers claim to hear a buzzing on their end.

It technically works - but it feels flimsy buttons are a little unresponsive, and there are extra buttons that don't do anything. I bought it exclusively because I wanted a larger remote that wouldn't get lost for a rental property we own. I wouldn't re-buy this.

Obviously its a Windows product BUT come on, I have a mac with dual boot. The mouse settings on PC are great and not so on mac. On mac the windows touch button doesn't do anything. Totally sucked. The wheel feels a little archaic. I counted 24 "clicks" or stages for a full wheel rotation. Compare that to say the infinite feel you get with a touch sensitive scrolling device. I hope you understood that last statement. The actual click feels a little cheap but overall the mouse is nice especially the rubbery material used on the sides. Accuracy is ok.

On the Windows side of things, I feel the Windows button is too far up forcing you to make a very specific move to touch it. IMO it should have been further back for quick an easy access. Sometime I feel that another button could have been easily integrated on the little ridge where your thumb goes, like a back button.

The price makes up for some of the problems mentioned above. So it's simply... ok.

i would give better reviews if it didn't hinder the buttons for menu and back.. you have to press buttons extra harder than you normally would.

I works great except the center directional and OK buttons are very clunky. You have to press hard and it makes a load annoying load click. All of the other buttons are as smooth as can be.

The side buttons does not align very well to my power and volume button and are tough to click. I can never really tell if it clicked or not but sturdy nice case over all and great feel. I would search elsewhere for a better fitting one but its works fine for now as a temporary protection case.

Looks nice and designed nicely but the leather part and the button part feels cheap. When you move it around, you can hear it squeak as gets rubbed against.

The botton ripped right off on my first try lol.

Not a huge deal, but doesn't say much about the build quality.

I had my mama sew the button back on =D

You have to hold the button what seems like forever for it to turn on.  Feels very brittle and cheap and like it will break if you press the button too hard. Wouldn't purchase again.

it feels nice and looks rad, but kinda faulty for example my scroll wheel doesnt work at all after about a month, upsetting, wouldn't recomend. The single click double clicks more than half the time too now.

Worked OK for a while, but the main button has lost some spring tension and picks things on its own.

and build quality overall felt pretty cheap and crappy, buttons didn't have nice tactile feel. I have since upgraded to a logitech g600 - it is hands down the best mouse I've ever tried and it's been going strong almost 2 years - I will probably use the g600 for the rest of my life!

Small and light. It almost feels flimsy. The buttons get stuck all the time. Especially the right and left arrows. I have to pop them back out with the edge of my nail. It does not have as many buttons as the original remote that came with my player so I can not do everything I was able to do before. It will have to do for now but I only see it as a temporary fix
