Astra Beam Blade
Like others here, this set can be used to retro-fit flat blades to cars that did not have them originally fitted. The result is one of the largest adaptors on test.
It also arrives separate from the blade and needs fitting, but at least it’s ready-selected. Instructions are a bit basic, but it performed well on the wet screen, leaving only fine lines at the top. A keen price makes this a good budget option.
