Good jig
Size: 11 Holes
The jig itself is great. The markings make it easy to be consistent; the design is well thought-out; and the build quality is good. I would recommend replacing the drill bit, though. A nice brad point will serve you better.

In the trash after a single use
Size: 11 Holes
For context, I’m a seasoned woodworker and always evaluate tools with the price in mind. This seemed like a good deal and in fact when it arrived, it looked and felt like reasonable quality for the price. Unhappily, the first bookshelf I drilled was off from side to side by almost 3 mm which would make a really wobbly shelf situation. It took a while to figure out what was happening, but I finally realized the metal bushings that guide the drill bit are so soft that they cored out from contact with the bit even though I was cautious to not put the bit in under power but to get it in the bushing and aligned before drilling. Still, the bushings started angling immediately. So when you then use those angled bushings to set the pin for the next series, it’s off by a little bit. Then the next is off by a little more…. By the time I drilled holes up and down a 6’ high shelf, the bushings were out of square, the holes were 3 mm out of alignment, and the shelf sides were firewood. Back to the drawing board and this goes in the trash, I’m afraid.

Finally, A Great Trackball for Macs
After reading the other Amazon reviews, I thought I would respond to some of the issues other reviewers raise from a Mac user's perspective. I run a new PowerBook 15" with OS X 10.3.2.
Unlike some other reviewers, I didn't notice any directional/orientation problems--the cursor follows the ball movement very well, even before installing the included Logitech software. Perhaps the necessary drivers are now universally available, or perhaps the Mac version is just better. Also, the "finger layout" has not proven to be an issue for me--I can use any or all of my fingers to control the ball without any cursor-direction problems.
The wireless function has proven flawless on my Mac. The reciever is a couple feet away and actually off the desk (no line of sight) and works fine. It was essentially plug-and-play on the Mac--I didn't even have to push the 'Connect' buttons to establish a signal, it just worked.
The software is necessary, however, to re-assign new functions to the several buttons on this model. As a former PC user, I can't go without a right-click button (one of the reasons I bought an external device for my notebook at all). The Mac software is very easy to use, and one can re-program all of the buttons and the wheel if one so desires. You can set a button to automatically double- or triple-click, or select keyboard shortcuts (e.g., Command and W to close the current window). Very easy, and quite useful--I use buttons to close windows, quit programs, delete files, and still have a handy web-browsing 'Back' button.
The only possible drawback to the Mac software is that one cannot "train" the ball's orientation (from what I can gather from other reviews, this option is not available on PC either). This really only matters if you know you hold trackballs at a different angle than most people do.
Please note that the software I'm reviewing is for Mac OS X only; the program for those running OS 8.6-9.2 is a different piece of software, which is also included in the package.
Those are all the Mac-specific comments I can think of at this point; if you're a Mac-user you're probably used to things "just working," and this device is no exception.
I'll also comment on some of the more universal issues raised by other reviews:
Ergonomically, there is a period of adjustment--anyone moving from a conventional mouse to any trackball or from one trackball to another should expect that. It's never a bad idea to try one out in-store to see how they feel, especially since trackball models vary from one to another much more than mice do.
This is not, as some have termed it, a 'disadvantage'--all new things take some time to get used to. If you've never used a trackball, it's weird for a while; it's also ergonomically superior/healthier in the long term.
Also, I use trackballs for computer drafting/design, and find superior control to mice--finger-control is just more precise than either thumb-controlled trackballs or wrist/arm-controlled mice.
The optical ball-tracking technology requires almost no cleaning, and there are zero moving parts to clean. Just pop the ball out and blow any collected lint out of the socket if necessary--which very rarely is.
For any pointing device that's wireless, optical, and has this many buttons, this price is pretty decent--lower, I think, than my previous trackball that was wired and lacked the wheel.
As for Logitech's reputation/reliability, I have had good experiences. My first trackball had to be replaced during the warranty period, but its replacement has lasted the four years since--I only replaced it now because it wasn't Mac-compatible. Now Mac-users can rejoice with a high-performance trackball that works seamlessly in OS X.

A treasure that desperately needs a reboot.
I love this mouse. I greet it every morning and give it warm caresses as I drink my morning coffee. I catch myself staring longingly at it daydreaming of using it sitting on a beach sipping a drink with an umbrella. I call her Bridgette. Is she perfect? Probably not - otherwise they'd still be a lot more popular. Is she perfect for me? Yeah. She is.
So first the bad and then the good: This mouse is big. For folks with normal to big sized hands, that's a win in a world of tiny mice built for Hobbits. If you have the hand size of a large doll could you still manage it? Yes. It's not THAT big.
The surface finish is...temporary. Dynamic. Fluid. I think of it more as patina at this point. Most of the painted surfaces (except for the left click button) on mine are still the same color they were when I bought it. I seem to remember a "soft touch" satin coating on the black parts but that has worn off mine years ago. She still turns heads though.
Some people say that these mice have reliability issues. We've been together for a good 17 years and she's still going strong. There was a scare recently where her buttons stopped working but a careful dose of electrical contact cleaner in the switches and a few hours rest and she was right as rain. She's not bullet-proof but hopefully will be around another score or so before parting for good.
What I love about this mouse is the feel. It's just right. Trackball people are a finicky group and rarely do we find something that suits us to little complaint. The size of this mouse fits me perfectly. All the buttons are where they should be, I don't have to strain and move and fight to make stuff happen. There's enough flexibility in programming the buttons you can set it to do most tasks easily with one click. It's not so complex that it introduces unwanted drama in your life trying to figure out the minutiae of endless setup options.
The trackball is perfectly placed. It's far enough forward my fingertips don't have to hunt for it and just enough to the side that I don't have to twist my wrist to reach it. I can swipe easily from one side of the screen (or across screens) without a thought but still have enough control to be precise when needed. All without straining my wrist.
I like the action of mouse clicking left/forward/back with my thumb as it's more natural than the thumb-driven trackballs. I either suffer from twitchy thumb or it's just a bad design for precise movement. The right click button is naturally placed just to the underside of the trackball and feels effortless to click with my ring finger.
The scroll wheel is small but cushy and comfortable. There are soft indents to the scrolling so it doesn't get away from you. If you prefer the smooth scrolling feel the "cruise" buttons above and below get that done easily. The drag lock button can come in handy if you're constantly copying multiple files back and forth. I generally don't so it's easily remapped in the software.
Battery life is really good. I usually go several months on a set of cheap AA's. It has an auto sleep function instead of a power switch which is handy. The nice thing about AA batteries is that you can easily find them anywhere. I think that's one of the main reasons mine has lasted so long.
Dear Logitech or any other company that may stumble across this - please bring this model back with a reboot. People obviously loved it and they sell like hotcakes. I've seen used ones go for upwards of $400 now. Surely there's some profit in doing another run of these beauties!
