I've been using this for 2 months now. Works great and I'm a heavy BB user (Curve 8300 model). The ball is black and does not allow any light through, which is fine by me.
The other reviewer stated that his/her trackball stopped working properly 2 days after installation. My suggestion is to clean the surface that the trackball sits on. After taking out your trackball, look at the surface. You may notice lots of hard-packed dust. That is preventing a clean contact between the trackball and circuit board.
I used rubbing alcohol + qtip to clean it, let dry, then install new trackball. It took 1 minute altogether, very easy. Black Trackball for BlackBerry Curve, Pearl, Javelin, Tour fit Blackberry 8300, 8310, 8320, 8330, 8350, 8800, 8810, 8820, 8830, 8100, 8130
Although this trackball has more of a cloth/grip feel to it, I don't mind because it works. My trackball went out in my Blackberry 8900. Note if you don't have a Torque 6 screwdriver you may need to purchase one.
I would recommend this:

I installed this trackball within a couple seconds after disassembling my Blackberry. Note be very careful with the screws, especially the black ones. I had the tip of one break by screwing it back in too tight. You have to screw it in tight to make sure the phone stays together but I think I turned that screw a half-turn too much. It was easy to install the new trackball because you just place it where the other was. Make sure that the small spoon shaped contact that's on the back of the trackball has the spoon end up and the handle down. That's the way the old one came out so that's the way I installed the new one. I didn't really need the trim bezel that comes with the trackball but you may need it for your install. My phone has the illuminated bezel so I only switched the balls out. Also note when reassembling your gonna have to hold the phone together tightly or it will pop apart until you get the screws back in it. When I reassembled I started with the top two, then bottom two and then the middle screws.

My old ball was just moving to the left and right, I had to take out the ball and kept on moving/switching/turning the ball in the socket to get it to scroll up and down, which I must say was very annoying. Hence, I decided on getting this which solved the problem.
I had no problem putting it in, it went in with ease. It moves smoothly, so far it works okay even though it has been a week since I've been using it.
I wish I'd bought a diff. colour because the black is so 'blahhh' but it actually matches with ma BB.
Thinking of getting a new BB, upgrading so I'll more than likely buy a diff. colour track ball if all goes well with this one, I hope the ball doesn't strip easily, if none at all.
Worth the money I paid for it at the end of the day.
P.S
I know black isn't a colour, It's a shade. :)

I had a problem with the ball this afternoon, it actually stopped scrolling up. I had to take it out and wipe it off and be shifting it around and then put it back in and it worked.
I really hope that after I left a good review I don't have to change it, that would be real disappointing and would feel like a rip off.
This trackball was a perfect fit to my Blackberry Curve 8330. It's been a week or two now and so far it's working great. There was no instructions for installation but it was rather easy, just point the tri-legs southward.
Blackberry trackballs are a gigantic nusence! Unfortunately for those of us that still carry around an old one that doesn't have the new trackpad, trackball replacements are inevitable. This one was ok; it hangs up a bit on the rollers, although I think it's gotten a bit better over time as the grease and oils from your hands loosen it up a bit. There might be some better OEM trackballs out there, but this will work in a pinch. I used it on a Curve 8900.
the product arrived on time, but in very poor packaging and without instructions, unassembled. After about an hour of trying to get it in my blackberry just so-so (it never quite fit) and it started fall to pieces and i'll have tiny microscopic screws in my carpet for the rest of my life. Now I am not, blaming them for my destroying the item, i'm not technically saavy, but they at least should have had a diagram or something so that someone without an engineering degree can put together relatively. My complaint is with the product, not the company.... - Curve - Blackberry - Replacement Parts - 8900'
