These are very basic panel blinds, but definitely do the job.  They block the light really well (keep the heat out) but still let the light through so it's not too dark.  I was disappointed that they don't come with a wand to move them, and you have to do it by hand.  Overall, wasn't willing to spend a lot on patio panel blinds and these work!

Pros: Easy to assemble, good value
Cons: No wand to move the blinds.
