Should we install a center divider on our double patio door?

We currently need to make a decision on whether to install a center divider on our double patio door. Until recently, I was of the opinion that it was better without one. However, our GU convinced me to purchase a mullion. The main argument was that a door with a mullion is more reliable.

What is your opinion on this? And your experience?

• double door
• divider on door
