I have had aluminium ones at a house I owned in the past. The slats are bigger and so are less cumbersome to dust.

Narrow slat plastic ones bend easily when you try to wipe them in situ, and as years have passed they are getting brittle.

These plastic ones have seen me through 9 years and were Glynn Webb cheapos, trimmed and fitted by me. I once was fit enough to take them down and soak them at least once a year. Now I don't have a bath to soak them in they are bothersome.

PS just seen your post Susie - will look for their website - thanks
