I used them once and they were, er, rubbish.
They broke some trim on the Volvo, took about a month to get a replacement part, then *I* had to take it to a body shop to get it sprayed, then they refitted it wrongly. They also got silicon sealant all over the bodywork. Total bunch of incompetents. I'd use Autoglass in future. They're also muppets but not total idiots.
Just my opinion of course.
