This product is terrible! Installed in 10 minutes after the dispatcher delivered the package at home! During the installation process, I found this by twisting the bracket! The bottom of this item is starting to warp! (Because it's hollow at the bottom) And when I tried to remove the bottom from the bracket. Because the bottom of this item was deformed, the bottom edge of the item cut my finger skin when removing! And it made the wound bleed! ! ! ! ! !If you want to buy this item! Remember to be careful! Also, the bottom of this item is hollow! Very easy to deform! When buying, please be careful to protect your fingers! I don't mind if you buy this item!
