We purchased this blade a couple of years ago for the boat. Tried it at home on the shower glass and it worked so well it never made it to the boat.
The blade is well built and still in very good nick after a couple of years in the northern Australian heat & humidity.
If the handle was black instead of red, it would hide the little bits of mould that inevitably turn up in a warm, at times damp, environment.
We are going to buy another one and with a bit of luck it will end up on the boat.
