Weather Shield does not deserve even 1 star. Buy these windows only if you want to replace them within 15-20 years. The seals break and cloud up. We've had to replace every window that gets any sunlight.
Their customer service sucks and they tell you, "sorry your warranty is up, we can't help you". I've purchased much cheaper windows that last much longer for a fraction of the price. Please save your money and go elsewhere.
