    Looks good in the bathroom.

    The quality of this product was excellent. Very sturdy. Easy to assemble. Just what I was looking for. When getting the paper towels, the base did not move all around. Highly recommend for the price.

    Lightweight but I like it
    Color: Black, Material Type: Stainless Steel
    Honestly fantastic for the price. It's just heavy enough to not get yanked around. It's pretty. And it has not looked like it has any wear or anything yet. I would recommend it. Especially for the price. If you want something a little bit more heavy duty I would definitely go with something else but I've had no issues

    It gets the job done.
    Color: Silver, Material Type: Stainless Steel
    These some on a flat piece of cardboard, and I was concerned. It goes together well, and has held up to Highschooler use for a month so far. It looks nice, but is nothing fancy. If you are looking for any sort of resistance for your paper towel for tearing, this product probably isn't for you. It is weighted enough for it to not fall over, it looks nice enough to be fine but not nice enough to want to steal. Exactly what I was looking for. If you are searching for the perfect paper towel holder... you probably will take issue with this one. If you just need a new paper towel holder, this one might do.
