NOT convenient to use.  Cool idea but they are just not practical to hold and actually use.  Too lazy to return.  Waste of money.

I could see the use for these but for me they are nothing but a headache. "Removable" is great, but these things have less stick than my bubble gum! I really mean that too, I took a piece of my gum to replace these dots that where just not working at a critical time. XD
I could see these working great for people who just want to stick a couple pieces of paper together though like a mock sticky note, so if you just want some light stick give em a shoot, but if you need any amount of "holding" power look elsewhere.

These look cool, but the odd shape and the completely smooth surface of these chopsticks make it really hard to use these.  I found them constantly slipping out of my hand when I would try to eat with them.  They try to combat this by giving the thick upper part you grip a slightly oblong shape, but it doesn't really help at all.

These are interesting. I like the idea of them but am not liking how they work. Firstly they are small and very tight on my hands. To the point of being uncomfortable. the first time I used them one of the sponges came off right away. Having the scrubby part on the back of the knuckles is awkward. as I do not feel I can get enough force behind them in that position. Would probably be better if one hand was sponge and the other was scrubber. They work, just awkwardly. I would like to see them re-imagined in a more effective manner and offered in sizes.

I received this product at a discounted price in exchange for an honest and unbiased review. This opinion is my own.

Cute.  Great idea but not very practical.  The little man doesn't go down far enough to really be effective.

When you write on these with pen, the pen scratches away the color coating. When you write on them with fine tipped markers (like sharpie pens), the ink never dries and rubs everywhere. cool idea, not great in practicality.

They work fine. They're just not comfortable and look a bit antiquated in design.

Great Idea is that just don't let the kids keep it. Problem is the design the color lens are not held tight just 3 wide slots. The child turns the lens holder and all fall out. Then there is the issue of lens getting misplaced. The learning the primary colors turn into big headache and had to put them awayt. I should have look for a design where the lens are held together but remain manipulative.

I purchased two of these. One has a whole after we used it once. On grass not rocks concrete or any other surface. They are neat but no way are they like what you "see on TV" more difficult to use and lose air quickly. Basically have to blow them up every time you get up from sitting on it. The concept is cool but not very functional.

Cool to look at but a little awkward to use, got it for my phone but didn't use it long as it is just not comfortable to handle as much as I use my phone.

This product has some good features but it is not a revolutionary solution. The product is very good for gripping and holding your items in place but you cannot rely on it to stay in place without holding it and air will leak out the top at high pressure so it will not work with high pressure applications.

These are really cute and easily get 5  stars for the idea, but only 3 for practicality.  Sure they store easily, but using them is more difficult than standard, boring cups.  Standard cups have handles with the volume displayed on them.  These have no handles and the measurement is written inside the cups.  My over-40 eyes have to look a lot harder to see what size I have grabbed.  I think it would have been nearly impossible to see the size after using it for something like peanut butter or shortening.  I bought this set to give to some grandkids.  We used them to bake several things. Part of the experience was to teach them the proper way to measure flour and  sugar (gently scoop or spoon some flour into the cup and use a knife or the flat side of the scoop to remove the excess).  Because there were no handles our hands got full of flour, something that was never an issue with my boring cups. The one cup size was also harder for the youngest child to hold when full than a cup with a handle would have been.

These are good as a gift or for someone who does not do a lot of baking, but are more of a novelty than a serious kitchen tool.  I will probably buy more sets for gifts, but mainly for the cool factor.  I do love Fred.

Not as practical as I had hoped.  You really have to reach down into them if you store anything in this front pocket.  Not ideal.

cute idea  Is A Christmas gift so won't know how functional they are for a few months

I think because these are so small, they don't grip too well.

The idea is good, but they often hang up and won't swivel.  You need to keep light weight oil in them every month or so, so plan on that.

They are not very soft or comfortable to use, only for looks
