An update: I've had the Justissimo and the Bol paired for about 2 weeks now and my comments are as follows:
Great lid - very flexible, with flip front, good padding/sound proofing (better than my old V2) loads of vents, and the internal sun visor. Only negative is that it still mists up a bit when its very cold.
Adequate performance from the Bol-08, it paired OK with my phone and automatically answers incoming calls, and allows me to re-dial at the touch of a button. Battery life is good, fitting was a doddle. I can't get music from my phone to the bluetooth though, and I don't have a separate sav-nav, so I can't check that. It has auto-volume adjustment, and can be a bit quiet at speed, but slowing down a bit cures this. For £25 no complaints!
My lovely wife also bought me a Bol on ebay, so I have a spare if anyone is looking for one. Not sure what this says about our communications, but its the thought that counts!!
