It blends in with the bathroom, so it’s not noticeable, and it’s smooth and safe, which gives me peace of mind."

For my plastic cover, it’s still bearable, so I’m satisfied with my purchase."

"I bought this for my son who is potty training. He found flushing amusing and even managed to flush a toy down. After installing this device, it worked wonders! I got one for all three bathrooms. It's super easy to use for both adults and kids, and now I can keep the bathroom doors open again for potty training!"

"We purchased this device for my mom who has dementia, as she tended to overload the toilet with paper. After ensuring the surface was clean, I applied it, and now it works great!
