after visiting the shop twice asking for advice, it wasn't until the third visit that I found the manager to talk to. she boosted my confidence in their expertise enough for me to invest my money into putting shades in a lot of my windows in my new house. I installed them myself and, since i'm a bit handy, it only took a few hours. in the end my shades look great and will look great for many many years.
Pros: big selection, great advice (when you find the right person to talk to at the store)
Cons: almost too much to choose from, easy to get a sales person that's not that helpful
