Quality rubberised strip that does a good job. Far better than the other "seals" I've tried.
I never thought I could get excited by a shower door seal, but there's always a first time.

I never realised how much a good seal could improve my shower experience! The old one was cracked and letting water through, but this SIMBA seal is solid, easy to fit, and completely watertight. No more wiping down the floor every time I shower. Highly recommend!
