I went over to help my 87 years old neighbor change her indoor can lights with heavy thick glass bright bulbs so she could see better. She just had surgery on both shoulders, one after another or I feel she could have done it. There is a little trick- u have to twist the suction cups to engage release otherwise they hold onto that build with ample security. This must be a patented system because nothing I’ve ever used comes close. No more ladders- well except for extreme heights. Twist off at a slight angle- okay- can do. I’m just researching to buy one of my own. At $25-$30 it’s not cheap but I was as entertained as a kid at Christmas quickly changing over 12 bulbs in about 12 minutes, no ladders, a few twist of your wrist in each direction and the fun is over.
