I had to really push down hard on the button to make an adjustment, but at least it's sturdy, and the ends r white which is what I wanted.

I think these may get a bad rap because the push button to adjust the length is very tight. I used needle head plyers to hold the button down in order to slide the button into the correct hole.I didn't have the strength in my thumb to accomplish the task. Worked!!!

The windows in our rental house didn’t seem secure enough. This product has brought peace of mind that our kids can’t open them and fall out and intruders will have a more difficult time breaking in.
