Grabbed these in a hectic rainy/windy day to put on a line of car windows. They staid put which was lovely for my purposes. The texture is different so if you need something very smooth these may not be for you, but I love the texture and how my pens glide across the surface. To give an example of how it "feels" to writ on these, it is like doing a crossword in the paper versus writing on a copy of a crossword on regular printer paper (the regular post-its being printer paper).They feel thin to the touch and are mush less rigid than regular post-its, but don't be fooled because they will NOT easily tear when you are done with them. So all and all, they have great stick, I love the texture, they have multiple colors, and they are not flimsy. I'm a convert.

Does what it says on the tin. Note that 3M doesn't recommend using on normal paper, because these are SO sticky that they can damage some paper. It was difficult to write on them with normal pens, but the Sharpie Extreme (which is designed to write on plastic) worked great.

Exactly what you need for certain situations, work exactly as promised.As a gardener, I often want to label, things temporarily that may get wet. These are perfect! Regular Post-Its, even using waterproof ink, get mushy, and the glue fails, and as the paper degrades it can become unreadable. None of that happens here.I put a note written in black permanent Sharpie on one of these Extreme Post-Its and stuck it up inside a shower used by three adults and a middle schooler. After a week of multiple daily soaking, and occasionally being gone over with a squeegee, the thing is still there, in one piece, and bright and legible as the day it was written. Wow. The only "fail" was that the glue has *started* to be less firm, due to my daily lifting of the note corners to check the glue hold. [EDIT: That note lasted 6 months, before it finally fell off the glass. ;-o ]Most people say the material feels a little like blue painter's tape; not sure what it is made out of. It is rough enough to write on and takes pencil and ink well. (Warning: some inks run when wet.)A little pricey in smaller packets, not too bad in the larger pack. Still, not going to swap out regular Post-Its for these full time -- there is a slight premium for the specialty nature. But my goodness these are cool.

We used these to mark arena stadium seats for a reserved seating area during an event. They worked out really well and stayed put on the plastic, texturized seats. Be careful when writing with your permanent marker, as when the ink is wet, it could smear, but once you write on one post-it, you figure it out. Nice product.

Use these for notes on dirty lumber or woodshop projects when regular post its sticky are too light and not sticky enough. I keep a few pads of these next to the 10 or so regular post it note pads in the shop. I will always keep a few of them, but really to expensive for every day use in my view for specialized applications.So I do not use these for all things in shop or garage as they are over kill for most situations, but they do work when there is ALOT of dirty. They are pricey though and for 85%+ of applications regular post it will probably work.

Work well but I paid $6.87 for a box of 12 extreme post its, on Amazon, and they are $78 now? Ridiculous. Don’t even bother.

I was able to use a sample while at builders store, but unable to find them anywhere but here on AMAZON. These really stick to surfaces and you need to be care with paper because it will almost seem like a glue to the paper. I use these all the time. I am glad I got the 12 pack my friends love them too. The surface of the paper has a slight texture that is appealing too. I high recommend these post it notes for teachers who are needing to post things on the wall for a exit note or to place ideas on any surface. So I guess business people can use this these notes too.

I have very mixed feelings about these. The paper itself is an interesting texture and design. The paper itself is great, it's water proof and easily written on.The adhesive on the other hand is not. My whole purpose for purchasing these was to implement a system between my boyfriend and I. Sometimes our communication isn't where it needs to be so important appointments, bills, heads up, etc are placed on the fridge via sticky note daily. I got these ones because the front of our fridge is stainless steel and not magnetic. I was hoping it could stick to the cold surface with ease... WRONG. It I mmeadiately peeled right off. I gave it a real good stick and it peeled off and fell to the floor within 5 minutes. What the heck!?So I had to tape a piece of paper to the front of the fridge in order for the adhesive to work. The adhesive loves paper. It sticks like no other to it. So much so, that it peeled some paper off with it.So that's why I gave a 3. Because it didn't fully do what I'd hoped but with changes on my end I made it work.
