Therma Tru Doors

I am looking to replace my patio french door. I looked at Therma Tru doors, Fiberglass, can anyone advise pro or cons on this company? I know Anderson, Pella are the most popular, but $ is a factor & Therma Tru doors are much less $.

Thanks

 

I use to work for Therma tru doors the fiberglass doors I think were good doors but they are closeing the doors at the plant here in oklahoma

 

i think its just the plant here in oklahoma they told the workers they could move with them if they wanted to
