Just installed these sliding window locks and wanted to share my thoughts!

The good: Super easy installation - literally took me 2 minutes per window. No drilling needed, just screw them into the track. The aluminum alloy feels sturdy, way better than the plastic ones I had before.

The package comes with 4 locks and different key types (hex and vertical), which is great because I have different window styles. The extended length (2.4 inches) definitely feels more secure than shorter versions.

One heads-up: Measure your window tracks carefully! Some reviewers had issues if their windows had unusual bases. Mine worked fine though.

Minor complaint: They only include 2 keys total, not one per lock. Would be nice to have spares since losing the key would be a problem.

Overall? Great value for money if your windows are compatible. My home feels more secure now, especially with kids around.
