Let me start by saying this: the AVID POWER Cordless Angle Grinder is a beast when it comes to power. The 4-pole motor delivers serious grinding and cutting performance, making quick work of metal, tile, and concrete. I put it to the test cutting through some stubborn bike locks (yes, we had a similar situation to one reviewer!), and it sliced through like butter at 7,500 RPM.
The cordless design is where this tool really shines. No more tripping over extension cords or being limited by outlet locations. I used it for a backyard cleanup project lasting nearly two hours on a single charge - though your mileage may vary based on intensity of use.
Comfort gets high marks too. The rubberized 3-position handle gives excellent control whether you're working overhead or at awkward angles. Quick-change wheel design means less downtime switching between grinding, cutting, and sanding tasks.
Now for the not-so-good: battery life can be inconsistent. Some users report great runtime while others (myself included) notice significant drop-off after initial use. The battery protection system seems overly sensitive at times - I've had it shut off prematurely during heavy use.
The biggest frustration? Battery compatibility issues. Unlike other tool systems where batteries are interchangeable, AVID's batteries are model-specific. Getting spares can be a headache as noted by multiple reviewers.
Final verdict? If you need portable grinding power and can live with battery quirks (maybe invest in an extra), this is solid value. For continuous heavy-duty work though, you might want to look at pro-grade options with better battery support.
