Hello sarah! Thank you for sharing your feedback with us. We’re truly sorry to hear that the installation process took longer than expected, especially with the inside mount brackets. We understand how frustrating that must have been, and we appreciate you taking the time to let us know. Your experience is very important to us, and we’ve shared your comments with our product team to explore ways we can make future installations easier — including clearer instructions or tool recommendations.
