GROWNEERMini Cordless Rotary Tool Kit, 8V Rechargeable Rotary Tool, 5 Speeds, 117 Pcs Multi-Purpose Power Brushless Rotary Tool with Lights for Polishing, Sanding, Drilling, Engraving, DIY, Pet Nails

I do hardwood carving as a hobby and use grinders and other power tools as much as possible. For precise work I use small chisels and Dremels. Currently my Dremel 7760 is wearing out after a long life. Decided to give this Growneer a try. Cannot speak to its durability yet, but this is a precision tool for finer woodwork. The collet works nicely and the change of bit is really quick. Tool has plenty of torque for what I am doing at this point in the project. Battery life seems reasonable. Built-in battery means I can’t switch out and rotate batteries, like with my heavier duty Dremel 8220. Agree with comment that the cap for the USB charger is not on a hinge and can easily get lost in the saw dust. Slim design allows for a great feel as I am carving.So far I am very impressed.

I love the quick change feature and the build quality. Extremely handy tool that runs strong and has little vibration.

Very strong tool. On/Off button is a little confusing but manageable.

The weight and finish are impressive right out of the box. Quick locking collet is very fast and easy but longevity is a concern. Battery life is very good and lots of polishing can be done on a single charge. Cordless means it is incredibly convenient, just grab the tool, insert a bit and go to work anywhere. I really like this tool.

Awesome product with some heft. Came so well packed with box, case and tool all wrap sealed. It's So we'll made I had to look to see if it was made in Germany, but surprisingly it was made in China. The quick lock collet is a fantastic feature. Motor is strong batteries are rechargeable. The storage box is plastic with surprisingly two layers of multiple attachments. I don't normally write reviews, but this product deserves it.

This rotary tool is SO handy. It comes in a sturdy case that neatly organizes the numerous tips that come with it. The battery has proven to hold an adequate charge to finish my project every time I have needed this. I love that I can just grab it and go. It does the job just as well as my old Dremel and I no longer have to drag along an extension cord or move my project next to an outlet. So convenient and available for such a reasonable price.

Round shape of grinder rolls when placed on flat surface. Would be better if one side was flat to prevent rollingHard to start unit. Button takes several pushes to start Once started it works well

TLDR: AWESOME MID SIZED ROTARY TOOL THAT IS STRONG AND EASY TO KEEP EVERYTHING TOGETHER + USB C CHARGING. YUP! WINNER WINNER CHICKEN DINNER, RIGHT HERE.Detailed Review:I am a Contractor and Business Owner and I handle tools for a living. I am usually very “critical” of off brand, generic or unknown manufacturers of tooling. Proven by ALL of my past reviews, I am not one to sugar coat things and I call it how I see it. Staying true to that notion; here we go.This rotary tool surprised the heck out of me. Being an unknown manufacturer and the price, coupled together, I automatically assumed it was not going to be good and probably going to be not worth it. I was WRONG! This thing is actually pretty torque-y and strong! For instance, I have to put a LOT of pressure on a sanding drum to stall this tool out and it has a built in shut off to protect itself and the motor! NICE! It has speed settings that need to be cycled through every time the tool is turned on and off but that is no big deal due to how good the actual tool is. The “quick change self locking” collet on this is GENIUS! Super Easy to make bit changes and they stay in and do not slip while in use! The tool also actually feels SOLID and built tight. Nothing cheap feeling or flimsy about the tool. Now the case…that’s another story. While it is a “nice case” and it keeps everything together, organized and easily accessible it is made from some rather thin and bendy plastic and I do not see it lasting all that long in my hands. Now for other people it may last long but due to being a Contractor, my stuff gets used and carried and tossed in and out of bags and tool boxes and this case will 100000% fail, crack or split on me at some point in the not too distant future. YMMV with this aspect of the item though.The tool comes with a rather comprehensive set of bits for all sorts of tasks. In my opinion it is a good broad spectrum kit that should have a little something for most any task and is a great starting off point for most. Making this an excellent choice for people who don't already have a dremel tool and are looking to get into one without having to buy a ton of extras along with it. The bits that come with are not the worst I have seen either. They are obviously not top shelf either.I have all sorts of rotary tools but this one fill the “sweet spot” in regard to size and power. It is perfect for grooming the dog's nails! Super portable, battery lasts and the lowest setting is great for this task. I also love the USB C recharging so, literally, everywhere I go I can charge this if I need to. Plus it has the storage I need to have bits with me that I need all the time. It is literally the Perfect Grab & Go Rotary Tool with enough UMPH, power and speed to get the job done. All without having to fiddle with a collet wrench or other types of collets that let the bit slip when being worked.The only thing I am not a huge fan of is the charging port cover is not attached and it held in place with a magnet. I can see myself losing that little piece easily while working along one of these days. I do wish that was tethered to the tool somehow but again, not a deal breaker because the tool is actually really good.I would absolutely order this again and I would recommend it! I unfairly casted doubt on the tool and I am very happy with what I received. This one is a winner folks!
