Good for what it is made for.
Forgive me if I seem a little preachy, but quite a bit of people misunderstand what this tool is for: this is a high speed, LOW torque (in other words, do NOT apply excessive pressure), LOW amp (not much mechanical power), multi functioning rotary tool. Dremel will most likely NEVER make a rotary tool that is high speed high torque, high amp, because that's not their niche. This is for weekend warriors, do it yourself-er types, this for crafts and hobbies, this is NOT an industrial grade spinning tool, if that is what you are looking for, get a die grinder, angle grinder, flexible shaft motor tool, get high powered electric or pneumatic, Milwaukee, Foredom, Ingersoll Rand, something else, not Dremel. You'll only be disappointed if you go the Dremel route with that expectation.
For Dremel's, you let speed do the work. Unless you are dealing with plastic or wood, something that melts or catches aflame, then go for high speed. Slow down on metal, speed up in ceramic (don't quote me on the ceramics, that's just my experience), go middle ground for wood, slow for plastics, and so on. I suggest ramping up the speed on a practice piece of the material you intend to remove stock from, until you reach the maximum speed you can achieve with ruining the substance in question, and then, go work on the actual piece.
Here, let's cut to the chase: Positives of Dremel 4000
+It is low powered, ergo, gentler on your work, more forgiving when you make a mistake
+It is very speedy, but not TOO speedy, as in, not a pnuematic die grinder spinning at speeds that would make a bullet cringe.
+Dremel has a ridiculously nice supply of accessories for it, good from jigsawing to power planing
+It is a multi tool extraordinaire, capable of many different tasks
+Ergonomic and very useful overall, a pleasure to work with
Negativity about the 4000
-It is pretty loud for its miniscule size, a downside if you have sensitivities to noise like me
-It is low torque, so you should not use force to get work done faster
-Low amps means it is not powerful enough to hold its own in large amounts of material without choking on its carbon brushes.
-It is a multi tool, not a tool, so it will never be good enough at one job alone to be a keeper in THAT respect
The Dremel works smoothly, without a hitch, at least in my case. If I were to recommend any 2 accessories/attachments, I would get the detailer's grip, and the almighty keyless chuck. The chuck, because it is time saving in the extreme, and time is everything to the discerning hobbyist/artist. The detailer's grip, because the flex shaft has that irritating extra hassle in terms of set-up, and is less ergonomic in my opinion, AND, most of all, cannot stand a kink of less than five inches without overheating, so it really is more trouble than it is worth, to me. So, altogether, I would recommend this tool to any doing small scale, hobbyist work, DIY'ing, and similar stuff. That's all she wrote. Peace.

Garbage, surviving on a reputation no longer deserved.
By Joseph Befumo
There are few things that enrage me more than companies that ride on a once well-deserved reputation for quality in order to sell utter garbage to unsuspecting consumers, and Dremel fits this description perfectly. I still have my previous two Dremel tools -- purchased in 1993 and 1995. Both still work, but are showing their age, so I bought a new one. It lasted less than six months before seizing up. I opened it up to see if I could repair the problem, and found that what was apparently a plastic bearing surface had melted. I use the tool for light-duty work in my electronic fabrication hobby, so it's not as if I were abusing it. This item is trash, pure and simple, and it's emblematic of the reason that "Made in America" has been reduced to a meaningless marketing ploy by dishonest bean-counters.
