Works as expected.

  • Familiarity: I've used it several times

Works as expected. Giving three stars because I don't recommend screw gates. The screws are so loose on these I've seen them unscrew on me which is scary. Do yourself a favor and use the auto locking. If you're unconvinced, these are a good option.
