260W Rotary Tool Power Die Electric Multi-function Grinder Carver Set, Stepless Variable Speed Adjustment, 31000RPM, Lightweight

I have many years experience with many different types of rotary tools. Foredom flax shafts, assorted dental lab grade micromotors, belt driven dental drills, 2 different Dremel tools, vintage electric hand grinder. I am familiar with care, maintenance and even some minor repairs of these tools.As of right now, after a couple of hours of use of grinding out some old rivets and wire brushing some hardware, I am giving this 5 stars, which could change in the future if it quits working too soon. I will probably use this a few hours every week and it should last for a minimum of 3-5 years, for a tool like this and the price.What this tool is good for... Smaller to some medium grinding, spot polishing, small part polishing, wire brush and sanding, rough carving work. This is mainly for more "rough" applications, not a "finesse" tool, but still more nimble than larger hand/die grinder tools. For what this tool is, it is fairly versatile little tool.Why I like it..... The tool has a very nice balance of size and power. It is small enough to use in "smaller" spaces. Running it for 15 minutes non-stop, grinding and it didn't get too hot to hold (I was concerned about overheating). After a few hours of on & off use and I still didn't encounter any overheating issues. It does get warm, but not unreasonably so.The chuck is what made me jump and buy this when I saw it. The grip is much better than any collet chuck on a typical rotary tool. I have been wanting something exactly like this tool for some time. The chuck and key are well made and work smoothly.What I don't like...... The switch. Wish they spent a tad more on the switch and charged a few $ more. It works, but it is stepped and NOT step-less and sometimes it is a bit "sluggish" when changing the speed. I haven't had any issues with it not powering on or anything. It does powers right up when turned on.What I wish it had.... A protective shield attachment like many of the smaller rotary tools have for use when using something like a cut-off wheel. Some users might appreciate it if it had a reverse setting, along with a true step-less speed control would make it more useful for carving. Another suggestion is to offer this with just the tool & key and no accessories and have another option with a case and a better accessory assortment at a higher price. (I didn't need the accessories. It doesn't come with any case, but I didn't need one either.)Honestly, I should have knocked off a star for the stepped, sluggish switch, but I want to encourage this company to invest in their grinders. I would love to own one of these knowing that it is of the same quality as a contractor grade tool like Dewalt, Bosch, Makita, etc.I will update my review if I encounter any issues in the coming months.

This is a pretty nice tool and the features that it comes with, But the only reason why im giving this four stars is because its a little weak. You go and start pressing down while using something like a wire wheel and it starts to bog down. Its not so weak where you can't use it, its just tiny bit weak. other than that the chuck is a nice feature, And it has two plastic screws on the sides of the tool so you can change out the motor brushes without having to take the whole thing apart.

Got this to port and polish intakes and cylinder heads. It works awesome for this job.

After the first usage, the switch stopped working to turn it on. I literally have to slide it back and forth which feels like a thousand times before it finally turns on. Thankfully I'm not an idiot and can fix it myself.

This end grinders are great for everyday use I use them when I grind metal and get rusty spots off with flap wheels witch you see here in this picture all I can say is it’s a tool that everyone needs

Probably should have returned this. Not much power. Gets very hot

The power is good also

Only reason i gave it 4 stars was because like some on here have noted, the power/speed button works horribly and requires a little flick here and there, but once you get that situated this is one of the most useful tools a hobbyist could want.
