  • 1 of 5 Not Good June 24th, 2026
    by madewell from Hudson, FL

    when I placed the order on June 2nd I paid extra for 3 day delivery. I did not receive my order June 16th not really 3 days it was 2 weeks. I would like a refund on the shipping and I will be returning everything to. It did not arrive in time and it was very important like I explained to the customer service people

    by Brian from Crested Butte, CO

    Way easier to install and adjust than a horizontal hinge. Probably a wash on price.
