Rated 2 out of 5 by from Needs improvement! This angle grinder is super handy, however, it will eat up a 4ah battery in no time. Also, it will tend to get hot or shut down when the slightest bit of pressure is applied. I ended up going out and buying the max power 4ah lithium battery which did improve its performance. The switch is in a strange position as well. Grinder was fairly inexpensive compared with other brands.

Rated 1 out of 5 by from No power Stops under light load ,no power needs to be replaced with a better product I have a lot of ridgid and this is probably my only disappointment with there tools

Rated 1 out of 5 by from Aucune autonomie de batterie et manque de puissanc Je viens d'acheter cette meleuse et je suis extrêmement déçu. C'est ridicule à quel point la batterie se décharge rapidement. En plus il y a un système de "cut-off" qui embarque aussitôt qu'elle force un peu. Pour couper une feuille d'aluminium de 1/8 d'épaisseur par 8 pieds de long, j'ai eu besoin de 3 batteries complètes, dont 2 grosses et une petite. Je l'ai acheté puisque je trouvais qu'il se tenait bien en main, mais c'est sa seule qualité... Je suis un fan des produits Ridgid, mais celui-ci est le pire outil toute catégorie que j'ai vu....

Rated 5 out of 5 by from Great grinder One of the tile installers I work has one and I loved using it. I I went out and bought two more and have gad no problems at all. I think the people that are saying it has no power are using 2ah batteries, when you buy it pick up the 2 pack of 4ah batteries so there’s always one charging. The switch it great because you don’t have to hold in on like the cordless dewalt.

Rated 4 out of 5 by from Fantastic tool. Great tool! Does what I need it to do. It burns through batteries quickly though, so if you have a big grinding job i wouldn't recommend it.

Rated 3 out of 5 by from Decent grinder for light-medium use, but expensive This tool replaced a regular corded unit that I've used for many years...while a basic version, that tool was about $30 and performed flawlessly for 6 years at least and still works great. This grinder, while it looks great and has a good balanced feeling in handling really stuggles with any loading being applied and cuts out much earlier than I would expect (as several battery tools seem to do to make up for the amperage limits I'd imagine). Battery life is limited and I find I'm using a 4ah battery more often to get the job done and I've found that some grinding wheels won't accommodate the larger nut that secures the grinding disk to the arbour so be conscious of that when purchasing grinding wheel for this one and if it's the type of disk that has a recessed mounting/contact area make sure the nut will fit!
