Saw this on Shark Tank.  They work pretty good.  The larger one takes some work to get around a large lotion bottle.

Not made very well

You have to work at them and they aren't fluffy but they do work pretty well and you can use the same pair for a good long while before changing.

They seem to work well.  It seems like a big jump from small to medium sized.

Does a pretty decent job, not perfect though, you have to kind of jiggle it a little. Definitely makes them faster than doing by hand!

These work ok.  At times they are a little sticky and are hard to use.  But for the price they worked pretty good.

I bought two of these and one was really tough. It was kind of hard to use, but the second was easier to use. Its not bad. Works well

One worked well to clean my bathroom.  Other one works well to clean my glasses.

The directions could be a little clearer, but I was able to figure it out and it works pretty good.

A little larger than I expected, but they do the job.

It works great.  . . but if I had it to do again, I would have gotten the larger one.

They work pretty well, however they have a couple little quirks to them that are a little annoying. Over all I like them though.

These are pretty good.  The adhesive might not be as strong as one might like, but they work well.

Not bad. I've used them a few times already and they have held up. I wish I would have paid the extra money and gotten the bigger ones.
