Magic Sponges Eraser,10 Pack Melamine Sponge in Bulk,2X Density,Long Lasting,Cleaning Sponge for Kitchen, Bathroom,Bathtub, Sink,Furniture, Wall Cleaner (White, 3.93x2.76x0.98in)

These do appear to be very dense. I use these almost exclusively to clean the sidewalls of sneakers for which they function better than just about anything.Vastly better buy than a brand name product.If any other reviewers say they “fall apart easily”, they aren’t familiar with these kinds of things. They are designed to fall apart like “an eraser as like a pencil eraser”. These definately don’t fall apart “easier” than anything else and on rubber sneaker sidewalls, they hold up reasonably well.

I think this works better than the national brand. It is thick it does not come apart quickly when being used. I use it to clean tennis shoes and other cleaning applications. I think it's long lasting and works great. I highly recommend it for the price point

These are a good deal. Haven’t had any issues and they seem to be stronger than the real brand. I use them for everything you can think of.

I have been using these Magic Erasers since they came out. They are, hands down, excellent at cleaning almost anything you can imagine. One example of their cleaning power: I had a key fob for a car that originally had white words and pictographs on it. Over the years they had turned yellow from age and exposure to cigarette smoke. I tried several cleaning products on it and none of them could even begin to return them to their white color. I finally decided to try a magic eraser on it and it truly was like magic. With just a few quick wipes over it, they were sparkling white again.Alas, I have to agree with many other reviews here on durability though. These are supposedly extra durable but they really are a joke. I've had them crumble in my hands even when using on smooth surfaces with little pressure (not much pressure is needed, by the way). While cleaning the walls in my pantry, I accidentally (but lightly) ran the eraser over a wire shelf. It instantly put a cut into it.I found a different brand here on Amazon that claims to be more durable than the competition, so I just ordered some. They can't be much worse than these so-called extra durable Magic Erasers.

The BAISENJIE Magic Sponges are an excellent value for the price! They work just as well as the major national brand and have incredibly versatile uses. I even used them in my pool skimmer to catch and absorb algae, and they worked perfectly. Great for a variety of cleaning tasks!

I took a chance on these and Im glad I did. Less expensive then the name brand and in my opinion they are even stronger ans last longer.

it works reasonably well--but seems to shed the material of the sponge quite a lot. I've since learned that using any "magic eraser" product is bad for many items because it is almost like a fine sandpaper--that can actually scratch or wear down some things--don't use on flat paint for example. The particles also get into the water---bad for the environment.

I love these. So much cheaper than magic erasers, but the same quality. Works wonders on my walls.
