Solid piece of gear you should have.
These are not amazing but they are very handy to have. My last Dremel, a 4000, lasted around 12 years. I think that’s a pretty good value considering there’s not much price difference from back then to today. In fact, I feel like I gave even a little less for the 4300 I got today. I use mine every couple months or so. The only reason my 4000 burned out is because I was too hard on it. I had to cut out about 15’ of vinyl flooring from underneath a cabinet. I ran it wide open for over an hour. It was very hot and I tried to let it cool a few times but couldn’t due to other reasons. I overused the tool but it did the job. It’s been about a week and a half ago and I needed it today. Old Dremel is spent and I had to buy this one. I used it tonight and it did good, exactly how I expected it to run. Hindsight, I should have bought an electric die grinder to do the floor. Side note, I took the flex shaft off my old Dremel and put it on this one, worked good. I also took the knurled knob collet off this one and put it on the flex head, it also worked well. These will last if you don’t abuse them. I’ll update if something goes wrong.

Perfect tool, Perfect control
This was ordered for a specific project I was working on. I am a tinker. I was asked to redo a cedar chest that had been covered with laminate & the wrong type on adhesive was used. It was a labor & time consuming project. I also repurpose older wood items. This kit is perfect for all those small, hard to reach items. I have purchased additional attachments as well. The unit is small & fits well in your hand. It allows superior control VS a hit or miss on repairs. I have used it several times & never been disappointed with the results.

Great customer service!
This Dremel is a great tool. Unfortunately, the one I received had a faulty switch. I contacted the company and their customer service and support is wonderful. They actually provided me with an upgraded replacement set/kit to make up for my inconvenience. Very, very nice of them. I would highly recommend the Robert Bosch tool company for going above and beyond in replacing my faulty Dremel.

More precise speed adjustments.
Great tool. I plan on adding the cable attachment.

Very happy!
To start I followed the instructions and ran at top speed for 5 minutes to set the brushes, not entirely sure what it means except it helps to break it in for use. I have been using it quite often. And for long periods of time. It's a bit loud on the main setting required for my work, as shown in the speed manual. Overall louder than the crappy chicago electric brand I used, but I figure it's a good trade-off considering the extra power behind it. Occasionally the tools vibrate the chuck enough that it loosens. Something I can tell immediately, it gets incredibly loud, and though annoying on occasion it is happening less often now. Maybe because I am getting better at tightening it. Or it just needed some breaking in. I love being able to change things without a tool. While I work I was always misplacing those dumb wrenches with my old one. If I use too much pressure, the dremel will heat up fast. Took me a bit to learn to use it more effectively without this, though it still gets uncomfortably warm after long use. I don't know if this is normal... But I think I will ask the company. For me it's a bit heavy. After long use my wrist gets pretty sore. A bit big for my small hands. But manageable. I'm used to things being a bit big for me, a 5-1 woman 😂 The best part is it works. I read a lot of reviews before buying. I never got the hot smell people described, or just not turning on. The kit is ok, but not really anything I use much. Hubby was excited about the tool sharpening piece. I expect it will be used quite a bit for that. The cord could be a bit longer, but overall a great tool. Very durable. My first dremel ever. Had a few off brands before and always loved how many uses it had. This one, a dremel brand definitely beats the others by far. With Amazon it's always a win win. I'm sure defects can happen anywhere, but I knew if anything was wrong they would back me up. Glad I took the chance.

Nice Dremel
Made quick work when needed. Powerful. Decent length cord. Not much in the way of assembly required. Carry pouch in nice. Feel like that's missing a carry handle. Universal accessory fit. Used several hours at a time with no issue.

Feels solid.
I bought this specifically for grinding back burred and mushroomed metal edges in hard-to-reach places, and it’s been excellent for that. It has enough power to clean up damaged edges properly, but it’s still small enough to get into awkward spots where a bigger grinder just isn’t practical. The variable speed control is really useful, especially when you’re trying to tidy something up without taking off more material than you need to. The kit comes with a decent range of attachments and accessories, so it’s useful straight out of the box. It feels solid in the hand, and the little light on the front is more useful than I expected when working in tight or shadowed areas. A nice bonus is that I can sharpen my knives with it as well, which wasn’t the main reason I bought it, but definitely makes it more useful around the shop.
