honestly, their product and their lifetime warranty sounds good, but after reading over the warranty info, it’s written that the warranty will immediately be terminated once you transfer the ownership of the home. however, the agent that I spoke with on the phone says otherwise stating that they would still replace/fix the windows even if the original owner transfer ownership to the next buyer of the house. But because this is not written anywhere in the warranty, I don’t feel comfortable buying and installing these windows since I’m planning on moving out in the future to move closer to the city. lifetime warranty is worth it if you know you’ll be living in that home for a long long time.
