Dealing with Shuttermedic was straightforward and professional.
The only difficulty encountered was that the pins were just a bit large for the existing holes, installation took a bit longer than anticipated. Also, the louvers easily closed in a downward position but cannot be entirely closed in an upward position because of a tight fit. But I don't consider this a problem. I am entirely satisfied and most pleased I was able to find a supplier for the replacement louvers, which arrived on time and ready to install after being painted.
