Pros and cons

Pros

Two listed mounting methods allow a choice between a no-drill setup and a screw-anchored installation.
The claimed auto-close and one-hand release can ease passage while carrying a child or items.
Y-bolts are specifically described for round stair banisters, an installation detail not covered by standard pressure pads alone.

Cons

The listed 22.63-inch passage is narrower than the overall gate width, so bulky items may be awkward to carry through.
The bottom ramp creates a threshold to step over, despite the listing describing it as a smoother step-over path.
