Editorial Review
If you’ve ever wished for a smaller router that still had the power and accuracy of the standard models, Bosch made this for you.
This little Colt is little only in size. It’s 5.7 amp motor gives you all the power and speed of a big bruiser, with a variable speed of 16,000 to 35,000 rpm. Weighing in at just a hair over 3 pounds, it feels like a feather, so one-handed control is absolutely perfect. Bosch’s soft grip design is intuitive, and whether your hands are big or small, it fits just right, giving you complete control. Don’t worry about torque at startup, either, because the soft-start feature cushions it beautifully. The base has indentations that Bosch calls "finger support pockets," and they really do lend a great deal of control.
The collect accepts standard ¼-inch bits, so you’re virtually unlimited in the bit department, with a surprising maximum diameter of 1-5/16 inches. There’s a spindle lock on the front, so changing the bit out is a simple one-wrench operation. The speed dial is mounted on top of the tool body, and while some would prefer it closer to the grip, we don’t see a problem, since you’re gripping the tool with just one hand anyway.
Depth adjustment is among the easiest we’ve seen on a router. Just turn the motor till the triangle and "unlocked" symbol align, lower the motor to desired position, turn the motor so the triangle lines up with the "locked" symbol and close the clamping lever. If fine adjustment is necessary, it’s a breeze, courtesy of a wheel on the back of the base. Done.
We can think of hundreds of uses for this little workhorse, but those who’ve previously been intimidated by routers will absolutely love it, because it performs like a full-size router, yet it’s a fraction of the size and weight. It would be perfect for rounding-over deck planks and railings, hinge mortising, making decorative edges on hobby wood, and furniture, cutting slots, for use with a dovetail jig, making window cutouts, decorative inlays, trimming laminate and more. Pros, do-it-yourselfers and hobby woodworkers will all wonder how they got along without this little tool. -- Kris Jensen-Van Heste

Two thumbs down. 
2008-07-22
No stars for this router. It has a funky adjusting mechanism to adjust the depth of the router bit. You release a lock, twist the housing to the unlock position, then move the base up or down, then twist the housing back to the lock positon, then engage the locking lever. I have a little over an hour of actual use and the adjusting system is beyond redemption. I turn on the router and the vibration causes the base to slip. I can't lock the router bit in place. The router is now useless.
Very light for those jobs where you dont want a large router 
2008-06-07
Recently added this to my tool box. Sure is nice to have something you dont have to try to hold up or hang on to when you dont need all that bulk behind a smaller bit. This router enables you to have more control when routing because of it's size. It's great for laminate trimming and small inlay work. I should have gotten this a long time ago!
Shaft-Lock button is horribly designed. 
2008-05-29
As others have said, the shaft-lock button is a major flaw to this otherwise perfect little tool. The flaw is such a pain that I really wanted to give it 3-stars, but everything else about the tool is so great, that I had to give it 4-stars.
When you push in the little red shaft-lock button, it catches on the aluminum motor housing, preventing you from fully engaging the button. Once you realize what is going on, you can work the button in such a way that it doesn't tilt to catch on the housing, but it isn't easy to do this. By the time I'm done fiddling with it to get it fully engaged, my thumb has lost the strength in it to hold it engaged against the strong spring until I get the wrench on. If the button comes out just a little bit, it will immediately catch on the housing again, and you are back to square one.
I usually just end up using a stick of wood to press the button in the end, propped against my belly to apply the force needed from my missing third hand. I really shouldn't have to do this. I'm just glad I don't have to use this tool on a daily basis.
Other than that one flaw, I can't think of a single thing wrong with this tool. Hopefully, Bosch is listening and will fix this flaw in the future models.
I rarely need my big router anymore 2008-04-30
This is my second Bosch product and I must say I am hooked. This is one smooth, powerful, easily controlled router. The soft start feature is great. There might be a slight learning curve with the whole depth adjustment mechanism but it really seems to make sense. This is slowly becoming my "go to" router
Could be better, especially from Bosch 2008-04-23
Small, lightweight, powerful, smooth and easy to use for small trimming and routing jobs. I have used it to roundover edges, form edges, mortise hinges and lock templates, and cut slots in plywood. Plenty of guts to get the job done. However, no matter how tight I make the clamp, this router eventually loses the bit's height adjustment. While rounding over the edge on a tabletop, the first side is flawless. Then, as I proceed to the second and third sides, the baseplate moves upward and the bit leaves a small edge on the edge that has to be sanded smooth. Also, the stop that holds the motor shaft while I loosen or tighten the collet does not function properly. I actually have to exert considerable force with just one finger on the stop button to keep the shaft locked so that I can tighten or remove the nut that holds the bit in the collet. The wrench that Bosch supplies is an ill-fitting one as well.
This could have been better. Bosch stopped just short of getting it right in my opinion.

Bosch Colt 2007-12-23
Delivery was very fast and product was exactly as described. Very satisfied with both.
Changed mind from 3 to 4/5 star assessment 
2007-12-07
I first wrote a 3 star recommendation for this, because the unit worked well in some ways--the small size is very handy--but it also seemed to me to have a design flaw. I took the tool back, because my initial impression was that the motor could not be secured firmly in the base. The result: a shifting depth of cut, as the vibrations made the motor move down. After I looked to other reviews and called a senior tech at Bosch, I see that the depth will not be fixed firmly until you twist the motor in the base just so. Not sure I can change the stars, but I see that I can change my text. I'd go 4 or 5 stars now.
This still seems like an unfortunate fact about this tool. I suppose the manual spells it all out, and I could just blame myself. But it would be good if Bosch could flag this issue. Anyway, once past that, I think it's a great tool to own. If you only want to work wood, get the cheaper PR10, which is one (fast) speed. You'd only need to slow the router's speed for acrylic or something that might melt or burn at 35K rpm.
One other shortcoming: can't use 1/2" shank bits. The Colt only takes the 1/4" bits, but that the case with all these small routers.
Making the Bosch Colt Work 2007-12-05
I've owned this router for about 6 months. I bought it because of the stellar reviews, and I wanted to supplement my Porter Cable laminate trimmer. For fun, I bought the whole kit.
Here's what I like:
1. The soft start feature is nice, and I like having variable speed.
2. The router is comfortable to hold.
3. Cutting depth adjustments (once you figure it out-see below) are easy and accurate (especially compared to the PC laminate trimmer.
4. The router has enough oomph to do what I need it to do. It's not a full sized router nor do I expect it to behave like one.
What I don't (didn't) like, and what I did to make it work for me:
1. The spindle lock is, well, not very good. It's very difficult to hold the lock in place while loosening the collet. Using a small wrench to hold the spindle is the way to go (see other posts).
2. The base locking mechanism didn't seem to work at first...the depth of cut kept slipping. Then I noticed you need to twist the router in its base into the locked position (marked on the housing). If you do this, the depth does not slip.
3. Inserting the router motor in the base is a pain. The small pin in the base needs to align with the slot in the motor housing. The action of installing the motor in the base seems "wrong"...it's not a smooth action and feels like it needs to be forced. By adjusting the locking lever (loosen it) and by paying attention to the locations of pin and slot, I'm almost used to the operation. Maybe after another 100 or so insertions it will be smoother.
4. The square base that comes with the router is too small and it won't take a routing collar. Spend the $10 on the round base...it makes using the router much more pleasant.
I'm not going to throw it away, but I wish the spindle lock and the motor-to-base fit were better.
Last bit of advice (especially for a small router, but realy for all power tools): Purchase bit & blade cleaner and use it regularly. Buildup on the bits really kills performance of the tool.
I returned mine 
2007-11-21
Like many others here I had problmes with installing and uninstalling bits using the lock button. It slipped so bad on the first one I got I thought for sure it was defective and returned it within an hour. The second one was better in that I could lock the spindel for a bit insert. I couldn't however get the bit out without taking off the base and using two wrenches. The locking button didn't lock anything going the other way. Not the convienence I expected and since the button is plastic it would have surely gotten worse as it wore down. I also had the base collapse damaging my project and then had a bit fly off ruining an expensive piece of material (not to mention the gouge in my stomach). I sent the second one back too. I've previously had real good luck with Bosch products, especially their jig saw, and will buy their stuff again, just not this item.
