Good: Everyone/Everything but the sales people.. Bad: Sales people's theatrics - need to sign now or price will go up; Gave me a really hard time when I cancelled initially. I only bought them after they gave me a discount.. Improvements: More honest sales people. I think the windows and the lifetime warranty are worth it. Especially the service. Keep up the good work and word will spread. You don't need dishonest salespeople to sell..
