Price? Cheaper than you could imagine. I can get these at the dollar store sometimes, so it can't get better than that.
Effectiveness? So so good. I'm the kind of girl who hates cleaning with a passion, but this makes my life so easy. No need for any chemical products that burn my hands, no need for soap, no need for anything other than water. Cleans any surface, super easy to use. 10/10.

We love Mr.Clean Magic Eraser!! It's definitely part of our everyday cleaning routine.
I have a very energetic toddler running around which gets into a lot of mess's. She's coloured on the walls multiple times with pens, crayons, markers, you name it and the first thing I'll grab is a Mr.Clean magic Eraser.

I use these magic erasers on quite a variety of messes. They work really well and last a reasonable amount of time. They are great for getting crayon off of surfaces.

Ceci est la plus merveilleuse invention!!! Il enlève 99.9% de toutes les taches que ma fille peut faire dans une maison. Rien ne lui résiste ou presque!

I love my magic erasers to help with all sorts of cleaning struggles around the house. From crayon marks on the wall to stubborn burnt pots and pans, they make everyday cleaning so much easier.

Mr Clean magic Eraser can make an old pair of worn white running shoes look amazing again! I use it on the rubber areas plus the white leather. It even does wonders on all my high heel scuff marks!

Très bon produit! très efficace j'utilise mes effaceurs magique pour tout laver le bain , la douche , tâche sur le mur avec ce produit tout part faut juste faire attention de pas trop frotter quand c'est de enlever des tâche sur la peinture !

Love this magic eraser, it has saved everyones lives in my house. Not really, but all the marks on our walls that we couldn't remove, we managed to get rid of with this eraser.

This Eraser works wonders on practically everything. I have used it on walls, in the shower to get rid of stubborn grout, even on fingerprints on walls. Just recently I used it to get my sons sneakers looking brand new. The rubber on the bottom was looking, well you can imagine and just a little elbow grease and the Magic Eraser and they looked brand new again.
Definitely always keep some in the kitchen, bathroom and laundry room.

I use magic erasers for everything. From scratches on just about any surface to cleaning grime off of my sink and stove! This product is amazing, I will admit that I have wasted money on the cheaper brands but ended up resorting back to the trustworthy Mr.Clean Magin Erasers.
