    This home bar looks absolutely amazing in my space and adds such a nice, stylish touch to the room. It was very easy to put together the instructions were simple and everything fit together perfectly. The quality is great, it feels sturdy, and it really elevates the overall look of my home. I’ve already gotten compliments on it, and I couldn’t be happier with this purchase. Highly recommend if you’re looking for something functional and good-looking!

    The cart looks really nice with the glass. It took some time to assemble. Nothing too difficult, just took time to screw everything in. All pieces arrived and the glass was packaged well so it wouldn’t break. Perfect size and a great price for the product. Highly recommend!

    Love it!!

    Tips for assemble at the end! I have to say, for as affordable as this piece is it sure is beautiful, easy to assemble, and functional. I am really happy with my purchase. I bought this as a surprise for my husband. He has a massive bourbon & whiskey collection that overtakes his entire bar, and this along with a new liquor cabinet was just what he needed to disperse some of his collection aesthetically. Be careful upon assembly, paint can chip if you screw the hardware in too tight. Also, when you go to put the suction cups in for the glass make sure you counter the weight from underneath the little flap with your free hand as you’re putting it on bc if you don’t, you’ll push so hard that the piece you’re pushing the suction cup into to get it to pop on properly will bend and break. I pushed a little hard on a couple of mine, but they bent back into place. Just assemble with a light hand.
