Has anyone fitted 'Tropik' blind/flyscreen?

I need to replace one of the blind/flyscreen cassettes and these seem a little more affordable and available quicker than the Horrex ones.

-I'm also struggling to find Horrex that are not adjustable and come needing assembly?

It's going to be fun and games getting at the blind to change it anyway as on our van they are behind a panel - which may or may not be tucked behind the back of the lockers or may need the lockers removing too. The easier and less faff the blind itself is, the better..
thanks

p.s I wasn't sure if this should have gone in the self-build bit or not. apologies if I've posted wrongly.
