Picked during Prime Deals and have no regret.
IMPORTANT! If your tool is flashing green when it is turned on, set it 10 to 15k and try again. Toggle on and if it still flashes try again. Now to the review. This is a great tool. It's got plenty of power and can SAND through a board. Not just cut. With a SANDING DRUM you can go through a board. It doesn't bog easily above 10krpm. It is great for cutting bolts, cutting sheet metal, sanding metal and wood, rough and fine shaping in wood. Fine shaping in aluminum, polishing steel, rough axe or lawn blade sharpening, engraving, and much more I haven't done yet. The battery life is good, but it leaves some to be desired. It can be gripped like a golf club for grinding, and shaping, or like a pencil for fine and detailed work. The battery charges in 30 to 40 minutes. It is quite heavy, but not enough to stop most detailed work. I can't say much about durability, as I've only had it for a week, but I've got it covered on sawdust, metal dust and splashed with water lightly. This is a brushed tool, but there is not a way to change brushes, so I guess you replace it. Fine with me for 70$, but might be a deal breaker for some to replace every 150 hours. It is a great starter dremel though. You will have to buy a lot more accessories to fuel your rotary addiction, but at this price it's pretty easy to. The carrying case is a huge bonus. It fits my 110 piece accessory kit with the charger, tool and battery. I overall, a great buy.

Very High-quality tool, everything you'd expect from a Dremel.
There's a reason the name brand is synonymous for the rotary tool, they make first class rugged quality tools that are the best at what they do. The device is easy to use, switching out tools is intuitive and simple. The battery life is surprising for its small size and the power output this Dremel is capable of. I would stipulate that this is not a beginner Dremel, you've got to really know how to use a rotary tool already for this, it does not come with labels or instructions for the different tools. I would personally also like to have seen more cutting discs included and some other grinding and sanding heads as the selection is fairly basic, you should plan to purchase the additional tool set with this. That being said, it made short work of the galvanized steel aircraft latch I needed to alter and later in the day I was able to use one of the cutting disks to alter some Warhammer models. The tool isn't too heavy and can be used easily for detail work, however it is a bit long and bulky if you need to get in a really small space. It is far easier to use than a corded version, however. Overall, I would highly recommend this tool for nearly any application, you really do not need a more powerful Dremel unless you are planning on a long-term professional jobsite with a really high-power demand.

Great replacement for the 15 year-old predecessor.
This is replacing my last cordless Dremel that lasted over 15 years. This one is performing just as I expected. If I have a negative, it would be the bulkiness. Other than that, I like the variable speed and in my opinion it's well balanced.

Power and run time more than expected
Previous model was corded. Very impressed with battery powered speed, strength, and run time. Also, the removal of the cord makes odd angles, and tight spaces so much easier comfortable

Great little tool
This is a powerful little tool with multiple speed selections. It is not variable speed, you have to select the rpm’s you want. This was my first time using the Dremel tool and I needed to cut off a large bolt holding a pulley on a lawn tractor. It took a metal cutting blade and the highest speed but it got the job done. There are many different heads available for the tool but not included in this package I’m looking forward to seeing just how versatile this tool can be. The battery is rechargeable so there is no cord to get in the way and it seems to last a good while. Use all safety precautions because it would be very easy to accidentally injure yourself if not careful. My hands are small so I was more comfortable using both hands on the tool for cutting metal. I think it is a good choice.

Dremel always amazing
Great tool to use. A bit bulky but 12v supply with 35000rpm still available its worth it. However keep in mind that Amazon US supplies at 110V so make sure when ordering. I am still looking for a replacement charger to get the battery charged it is so upsetting......
