Concertia type blind issues!
A number of caravans have this type of blind, but I cannot see them lasting as long as the old fashion blackout type of blind. Although ours are not quite 3 years old, already on the folds you can see pin holes of light appearing.
IMHO they are not as good as the other black out type of blind as they let in more light on the sides which can be annoying early in the morning.
Noticed it this morning while lying in bed and looking up at the skylight. Can see the pin pricks on the joints. I am guessing I cannot see the ones in the side blinds as no bright light shining on them in the morning. Looks like I will be using a torch
to check as this is the third year and the "warranty" expires unless I can prove an inherent fault.

I am wondering if at some future point whether one could replace them with the more traditional black out type of blind? Do you have issues with this new type of blind?
