Trouble with Pulex rubbers, is that although they don't slice up and leave lines like Unger, they don't last a couple of days before they're rounded on the edges and "blunt" along the middle.
Then they don't glide and leave smeary turns.
I've tested loads and found Ettore are the fastest, smoothest glide.
Unger are long lasting as long as they don't get cut.
Pulex don't cut easily.
Syr are ok at everything.
So I've been using Pulex purely because they don't cut up easily, and they're cheaper than Ettore.
They still annoy me with their uselessness after 20 houses.
Used to get a couple of weeks out of Unger years ago.
So Pulex it is, sadly.
Best of a bad bunch I suppose...
I'm glad I'm going mostly WFP, because they quality of rubbers these days is miles off what it used to be.
