To be fair, I would rate them 3.5 stars, if possible.
I needed a mover with good insurance to help move an expensive piano and they were the only ones I found that didn't insure pennies per pound. They actually were insured for up to a million dollars, which was great.
They did great with the piano (phew), but did drop some new bedroom furniture I'd just bought (minus a star). They kept great communication while I was waiting for my claim to be paid. But I'd moved in January and it took nine months later (today) to finally get paid (minus a half star).
The staff was friendly and efficient. Maybe a bit TOO efficient, in hindsight. But it was a late night move and they ultimately came through in the clutch. I would recommend them if you have expensive equipment that you need insured but just don't mind waiting the 9 months it ultimately takes to get paid!
