Promising review: "I bought this for our shower, because my parents were coming for Christmas and my stepfather is an amputee. He’s almost 70, roughly 6-foot-2 and 250 lbs., (or more post-Christmas feast), and I didn’t hear a crash all week. He survived the holidays without any injury, and the handle is still in place. It was very easy to install, which made me leery because I felt like it was too easy. I can’t get a shower caddy to stay up without crashing, so my fear of being the kid who put in the shower handle wrong and causing a holiday catastrophe was a real concern — my mother would never let me live it down. But rest assured, this thing is easy and sturdy, and the price was great. Holidays are tight enough without my desperate need for karma points and parental approval making extra deductions from my bank account." —Erin H
