I HATE MOST SHOWER CURTAIN HOOKS. EITHER THEY ARE EXTREMELY DIFFICULT TO HANG OR THEY ARE TOO EASY LETTING THE CURTAIN FALL UNTIL YOU WANT TO RIP IT DOWN, BALL IT UP AND THROW IT OUT THE WINDOW! BUT THERE IS HOPE. THESE HOOKS ARE EASY TO ATTACH TO THE CURTAIN AND ONTO THE ROD. THEY GLIDE VERY EASILY AND SMOOTH AND YOU DON'T HAVE TO WORRY ABOUT THE CURTAIN CONTINUOUSLY HANGING HALF WAY OFF. I WAS REALLY SURPRISED AT THE DIFFERENCE AND NOW I WON'T USE ANYTHING ELSE. I HIGHLY RECOMMEND THESE HOOKS AND WELL DONE TO THE SELLER!
