Customers highly praise the product's functionality, noting it works perfectly for connecting curtain rods, especially in bay or corner windows, and helps hang curtains in awkward spots. Reviewers also find the product to be of good value and appreciate its appearance, stating it looks decent and provides a nice transition. While most find the size to be suitable, one customer wished it was a bit longer, and another mentioned the size was a bit large but still functional. Installation is generally considered easy.
