you guys know about these wiper blades???

Yea I found these a year ago and installed them on my 68. I like the look, but for what ever reason they dont work well in the rain... The right one doesnt even wipe the windshield. When I had the black ones on they at least worked, so I dont think its the arms. The car normally doesnt get driven in the rain, but given that I am planning a week long road trip with the car soon, it will probably get stuck in it. So I am going to use the refillable numbers here and give them a go.
