I read some really poor reviews of them when looking for insurance - mainly around cancellations and updating your status (car mods, new car etc), I guess you're more likely to post a bad review though. Also, they seem to lure you in with a cheap price and then when you actually go through their system the price some how increases 10 fold. I remember getting a quote for my M3, something in the region of £1k and then when you phone them up or whatever to go through with it somehow the price has gone up by 50%. As said, they aren't the only ones.
