First off, let me say these window locks are a game-changer! As a parent of a curious toddler and two mischievous cats, I was constantly worried about open windows. The EUDEMON locks solved that problem instantly.

The installation was ridiculously easy – just peel and stick the adhesive tape (which holds like crazy after 24 hours). No tools needed! I love that they work on all our different window types – our UPVC kitchen window and the wooden bedroom frames.

The adjustable length feature is brilliant. We use the shorter setting for our toddler's room (just enough ventilation) and the longer one in living areas where we want more airflow. The automatic locking when you close the window gives such peace of mind.

My only minor complaint? The buttons require decent hand strength to press simultaneously – great for childproofing, but my elderly mom struggles with them sometimes. That said, it's a fair trade-off for safety.

After 3 months of daily use through all weather, these locks still look and function like new. Worth every penny for the security they provide!
