    Sturdy, simple, bombproof bit of

    Sturdy, simple, bombproof bit of kit and I really do like the matte black finish. Nobody has broken themselves or hit the floor at terminal velocity whilst I've belayed them off of it so I consider that to be a plus and an excellent selling point! Solid design, I can't fault it.

    Have used this with both

    Have used this with both 9.5 & 10mm rope. Runs through quickly with both, I like it that way though and no problems braking. Feels really well put together, sturdy in the hand. I'd recommend.
