It comes in a hard plastic case that has foam in it for every item in the Grinder kit. Easy to move around and stuff won't get lose. The grinder is as powerful as a corded one and comes with 2 4Ah batteries. Just the price of the batteries alone is worth this. It's like getting the grinder for free. It comes with 2 guides for the grinder. Easy to take on and take off. Protects your and your hands. It also comes with a handle that you screw on. It can be screwed on in different places for lefties and righties. Speed select is on the battery. 3 different speeds top speeds with the trigger also providing speed control. Push the trigger more, the faster the thing goes until it hits the top speed selected on the battery. I am using this for my rusty car. It's over 20 years old now and has a bunch of rust spots that needs to be grinded down and cleaned. This works well for removing rust, cleaning metal, and cutting metal. That is all I use it for but I am sure it works for whatever uses you will need. This thing is a buy and I would buy it again if I need another grinder. Oh this also comes with some cutting discs, grinding discs and flap discs to get you started. It even has a spot in the case for discs just in case you forget.

Came w/fully 2 charged batteries and an assortment of grinding and cutting disks. The grinder's heavy, has a locking button to change the disks and a great box for storage. Tested it on wood, PVC and metal and ripped through it. Plenty of power, didn't bog down or bite!. Over all I'm very pleased with the feel and quality.

The cordless grinder makers it a lot easier to work in spa where a corded grinder has limitations. The hand grip is more use friendly. The batteries come fully charged and the tool container to heavy duty. I enjoy the varied speed settings that make grinding, cutting, etc much easier. Only concern is the cutting disks are mediocre and will not last long.

The media could not be loaded. This thing is a beast! For an inexpensive chinese tool, this thing is fantastic! Grinds and cuts everything I've needed efficiently. Came in a very durable case with a starter supply of wheels etc. Two 21v batteries, charger, two different guards, chuck key and more. I'm looking for more projects around the house just to have an excuse to use this thing!

I really like the angle grinder. Works really well and appreciate not having to have a power cord. Has 2 batteries and a charger and several different grinding wheels. Is a very quality grinder.

Great product, works as expected. The battery is long lasting and it is more convenient than cord grinder. It comes with everything you need and storage box.

This is a great tool. It's lighter and smaller than I thought, making it easy to control with a solid feel. It came with a stack of heavy-duty cutting and grinding discs, two batteries, and a simple plug-in charger (no big charging station). The carry case is much heavier-duty than I expected, with thick, sturdy plastic and great padding inside. Don't worry about the affordable price; this grinder is comparable to top brands.

Like most of you, saw the deal, needed a cordless guy for my welding cart and figured I'd give it a shot until I see the Lowes have the Kobalt 4.5" grinder/4ah AND 2ah battery/BIG brick fast charger, and case on sale again for 99.99$ but hasn't for a few months .. so I grabbed this guy. Used my USB-C testing tool that can test mah, amp hour, charging protocols, voltage/amperage input & out and a ton of other things.. to test the batteries capacity. Double checked them with my tool I bought to test my 100ah Lifepo4 deep cycle trolling motor batteries because I was sick of being lied to by everyone as far as capacity goes & both of these tools to test manufacturer claims were the best investments possible. --Test results were no where NEAR 4 Amp Hrs as stated on the battery and every in the description/page for this grinder. One battery barely passed 2amp hours, technically 2.53ah. The other was 1.94ah. basically half or less than half of the claimed 4ah your paying for. Not to mention the time it takes to charge with their junk charger is insane. That's why you're seeing 5-7 min runtimes. I then retested with my own Power supply I made and sure enough, same results give or take 0.02-0.04 ah. Again one had more than 50% loss. The other was about 35-40%loss. The stated RPM's are NOT consistent. According to my meter, max rpm is anywhere from 8,120rpm to 8,217rpm. Again, no where close to the stated RPM's or power. I stopped testing at this point and could careless how it performs, if I only get 5 min of grinding and takes 5+ hours to charge the battery, it's useless to me.. Best bet is to just buy a tool only 4.5" grinder from a reputable company and buy a 3rd party lipo battery and save some $$ but this is not it.. had it lasted longer than 5-6 minute runtime, I would of loved it for the price and just asked the company if it was a fluke my batteries were NOT the claimed capacity. But unfortunately it's going back and the DeWalt is coming home for 100$ since I have plenty of those batteries already! Look elsewhere.
