Buying a 2nd one for the bathroom! Stays EXACTLY in place but easily slides on any surface to where ever you want it!! NOT like traditional paper towel holder that fall over when you pull the sheets apart!!! Great value! Convenient! Stable! Easy to install!

I love it
Color: White
It has taken a few weeks to get use to- learning how to pull it and when so the paper towels come off right. The suction cups are amazing. If you need to release it- I just slide a butter know gently und them and it un suctions. Hopefully it lasts a long time.

Very functional for our family - We ordered a second one
Color: Black
We were happy to stumble on this paper towel holder after trying a few that just either didn’t look great and didn’t work well. We really like the black matte finish and the fact that the base is pretty heavy so you can actually tear off a paper towel without the whole thing toppling over. The spray/cleaner is an added bonus to have right there also. It’s awesome for craft time and cleanup after kids. We purchased one for both our kitchen table and our rental property and they both function great and have been holding up very well. Happy with the purchase!

Amazing - Buy it!
Color: Black, Color: Black
This item is so helpful! I am a home baker and practically live in my kitchen. So anything to help me clean quickly and efficiently is a MUST. The holder itself is sleek and super cute, the matte black matches my decor perfectly! Having the mini spray bottle you can fill and place directly in the holder makes everything so accessible! I don’t have to pull out cleaners, then paper towels, it’s all a one stop shop. Plus, super helpful to clean as you go! This item doesn’t take up lots of space either. I will definitely be checking out other items from this brand to organize the rest of my kitchen!
