I ordered two of these grab bars. When I went to install them some of the tubes of glue had hardened. I emailed the company in the wee hours of the morning and had a reply from them when I woke up! I've never had such fast service. The replacement tubes were sent by the next day and I had no trouble installing the bars. The instructions were very clear and the bars are still holding securely after using them for several months. I did find the price was expensive but they were just what we needed because we are renting and could not (and wouldn't want to) drill into the tile in the bathtub. I would not hesitate to buy them again.
