We are very pleased with the Rollshutter system we installed. It has solved a major problemm we had with leaking windows whenever there was a heavy Nor'easter. The company was prompt on installation with minimal difficulty. The only reason we do not rate it 5 stars is that they did not warn us against rolling the system all the way up if it was covered with ice. We did and broke the "hangers"; however, the company came quickly, repaired the system and was very reasonable about the charge. We are very happy with the system and strongly recommend it.
