I've had 3 or 4 now. Much better than Metz and longer lasting. Tried the Bridgestone Exedra and was terribly disappointed so went back to the Avon. Mates really well with the Bridgestone on the back. Plenty of us are using it; Hanso, Mitch, Peter K I think and others. Lots been written about them on here in the recent past.........
