### ⭐⭐⭐⭐⭐ Just what I needed
*by T***E on March 26, 2026*

These worked great, and we're very easy to install. They appear to be of good quality and the pressure is evenly distributed. And the price was great

### ⭐⭐⭐⭐⭐ Fixed the saggy old gas struts in my safe
*by D***C on March 17, 2026*

I bought these to replace the worn-out stays on my Sentry Safe, and they’ve made a huge difference. I was worried they might be too stiff or not fit the original mounting points, but they snapped right into place without any hassle. The 35lb tension feels just right—the lid stays open securely now without me having to worry about it slamming shut on my fingers, but it’s still easy enough to close. It’s a much cheaper alternative to buying "official" replacement parts from the manufacturer, and honestly, the quality feels just as good, if not better.
