Fits my window at 31 inches with no wobble, and the flap swings quietly instead of slapping shut at night. I switch it to out-only in the morning so she can't wander back in with muddy paws.

The 4-way lock has been a lifesaver at night — I switch it to in-only so my cat can come back inside but can't wander out at 2 a.m. Fit my window snugly and feels sturdier than I expected for the price.

The 4-way locking switch works fine and my cat figured out the in-only setting pretty fast. The plastic feels a bit thin for the price, and the lock slider is stiff enough that I have to wiggle it. It does the job, just not as sturdy as I hoped.
