I take my dog here to get groomed and I'd say that 1/2 the time I leave really pleased and the other 1/2 of the time I leave not so pleased.
A few times I've left and the hair is uneven or his nails are VERY rough, like they clipped them and didn't file them. They are SUPER busy all the time though, so I can see how they'd forget to do something.
This groomer was right by my house, so that's why we used them. They have good deals, but I think you could find a better groomer.
Acceptable, but not exceptional
