Rated 2 out of 5 by JacobDeanMetalSculptor 250 bucks by the time you buy an X4 battery set.
I was not happy when it only ran for 7 minutes on the batteries that came with my drill and driver. I like Ridgid because of the lifetime warranty on batteries and products. I bought two X4 batteries on sale for 80 bucks each (20 minute run time with those) and was quite unhappy when they were not under the lifetime service agreement. Uuhg---And the bigger batteries are heavy and awkward. I have used other brands of cordless grinders and liked them better, but you know, once you pick a brand, it makes sense to stick with it. ----this is not my favorite Ridgid product.

Rated 1 out of 5 by OrcPuP the built in protections keep this tool from doing real work
This tool will suck a newly charged battery down so hard and so fast ,that it will cut out and you have to wait for it to reset itself, 5 or 6 times cutting of a piece of 1 inch by 1/4 inch flat bar,which took 7 or 8 minutes. I have 4 batteries , 2 large and 2 small and it does it with all of them. My large drill, reciprocating saw, circular saw will do the same thing if you are working them hard. The grinder is useless for what it is intended , which is cutting or grinding in areas at heights or where corded tools are unwieldy. it is definitely not going to wear out , ever, because you couldn't do enough real work with it to harm it.
It is easy to warranty for life if you engineer protections into them that won't let the tool work hard.. I have a dozen rigid cordless tools and I am going to switch to Dewalt ,Milwaukee , or Makita in the near future.. If you make your living with your tools, be warned

I love this thing. It has the same power as a corded grinder but I can carry it around as needed.

I've fallen in love with this Grinder it does exactly what I expected it to do and also lasted longer than I thought it would. Its great in tight places, being cordless is great because usually I just need the grinder for a second to cut a nail or something in a renovation and not having to deal with power strips is great. more time on the job.

Rated 5 out of 5 by Fiberbuilder Compact, moderate power
A bag would've been nice like what's included with the corded model but the convenience of a grinder this compact and cordless is really nice. It's not as powerful as a corded model but it will push through what you throw at it as long as it's not overloaded. Standard battery lasts 15-25 minutes constant load.

Rated 4 out of 5 by lincoln302 Great tool to have
This grinder has plenty of power and has saved me many times. I use this tool mostly for fabricating and installing stainless steel equipment. The only problem I have with it is the switch placement. I would say this is a must have tool.

Rated 5 out of 5 by rockyou Good grinder to have
Grinder starts slow, must be so as not to kick out overload. After that it works great. Is not super powerful, and will not replace your corded grinder, but great for the small quick jobs. Also has a locking trigger, which is a nice touch. As powerful as any of the other cordless grinders out there.
