So, I bought this for myself because I (for some reason) decided to go back to college. Right now, I'm just taking a couple little classes to amuse myself, but I really wish I had this during law school for the exact reason I bought it this time around. I got it because I've always been horrible with notes. I would have different colored notebooks for each subject for my notes. Problem is that I would get lazy and wouldn't take out the appropriate notebook, so I would have a notebook where every 3rd page had a different subject of notes, and it was very unorganized. The Rocketbook allows me to upload my notes (pretty easily, by the way) and have them organized in any manner I choose. Since I use One drive, whatever I upload to my Samsung Galaxy phone also appears on my Galaxy tablet and Samsung laptop. Now, for the experience: I read a decent amount of reviews and found some helpful tips that were actually pretty handy. Yes, it does take a few seconds for the ink to dry. I'm assuming it's because the ink doesn't "soak" in like it does with paper. It does actually feel VERY close to a real paper and pen writing experience. It comes with a pen and cloth to wipe it. Just wet the cloth and wipe. I do think if you pressed too hard (as others complained about) it would leave a dent, so watch out for that. If you close the notebook while the pages are still wet from wiping, they will stick together. It won't ruin it, but just pointing it out. Figure out a way to keep your set together. The pen does not fit in the spiral on the pad. Like some reviews stated, you can swap the pen case for a Pilot G2 and it fits, but the original pen doesn't bother me. Since I already knew about these things from reading reviews, it wasn't a big deal. I considered it a minor inconvenience in trade for being organized. My only complaint is that there's not a thicker pen available for it. I use the thicker writing G2 pens normally. I think they're the 1.0 thickness. Anyways, not available for this. Only the .7 is available. I prefer thicker lines, but whatever. You can get packs with different colors here on Amazon, which I did get. I use the different colors for math (to get track of the steps I do) because I'm in Trig. However, some colors don't show up right when you go to scan it if you have a lot of light (glare) on the pages. All in all, I don't regret buying it and I enjoy using it. It's just one of those things that you need to figure out if it fits your lifestyle. FYI, I have the note cards and all of the above applies. I use the note cards for my son (he's 12 and in junior high). He has asperger's, and has oddly fixated on wiping the cards and making them as pristine as possible. My 4 year old thinks it's magic. Update****** After almost 2 months of use, here's my input. As I stated in my original review, the rocketbook was bought (and is) mainly used for college (trig) work. It has been used for random notes that I need to leave for my husband etc. What I said before still stands, plus the following observations: -Get a pen holder. I got a basic one (from amazon) that is a peel and stick (onto the rocketbook). I originally didn't think it was a big deal, but since the rocketbook can ONLY use the frixion pen, get the holder. It will help you to not lose the pen, and it helps you to use the right one so you don't just grab any pen and start writing. I've caught myself grabbing my G2 pens and almost wrote on my rocketbook. If you decide to get the other colors of frixion pens, the pen holders are small enough to where you can easily stack at least 4 to hold different colors. - figure out a way to hold the cleaning cloth with the book. It's a bigger pain than you think (and I thought) to keep track of it than you could imagine. However, the pages will clean with ANY moist ANYTHING. I held the notebook when my hair was still wet, and just my hair dragging on it did some erasing. That's a good thing, if you watch out. I keep my rocketbook in a little canvas tote with my laptop, mouse, calculator, and cleaning rag. That was enough to fix the problem for me, but then again it just goes from my house, car, and office. I don't go into a classroom etc -I use the rocketbook mainly at home where water is not an issue, but I can see that it could be an issue if that's not readily available. If you're unfortunate enough to have to write through all (35, I think) double sided pages in one sitting, have a little spray bottle of water with you. The reason I didn't get the rocketbook that goes in the microwave is because last time I was in college was pre-covid, and I figured I wouldn't have a microwave in my class......but everything (and I mean everything) seems to be proctored on the computer as far as college goes now. Think about if the water or microwave one is best for you. If I would've known I wouldn't have to go in campus, I would've gotten the rocketbook wave. I still love this one, but just saying. -after using the app a bit, I can say it's been awesome for my needs. It's as easy as holding your phone up to the page (it auto scans) and you click which folder it goes into. If you use a cloud like I do, it'll all appear. In a couple of minutes, my notes appear on my Samsung Galaxy S20, Galaxy tablet, and Galaxy laptop in one step. This alone has fixed my unorganized notes issue that I mentioned. -the cleaning cloth needs to be thrown in the wash (I just put it in with my towels) here and there. Residue builds up (duh) and it needs to be cleaned. -the pen does seem to run out of ink faster than the G2 pens I normally use. -the eraser on the pen is like magic. It doesn't decrease with use like a normal eraser. However, I did notice is leaves a residue, and unless you wipe with your finger really quick, it's almost like the ink won't "stick" to the spot that was erased. -I have not used this pen on regular paper, so I can't speak for that -heat DOES make it disappear! I wipe my notes off within a couple of days of use, so I don't usually have to worry about it becoming "permanent" (like the disclaimer states), and the book doesn't make it far with notes since I scan them almost right away. However, we recently had a warm day (yes, in February because I'm in Arizona) and I didn't think it was "warm" enough to worry about anything (it was like 85?) And my notes went away. Thankfully, nothing important that I didn't plan on erasing. I did read that putting your notebook in the freezer brought them back, but I haven't tried it. -make sure any stupid people in your house don't have access to the notebook because they will use a regular pen on it -watch your lighting when scanning. It can mess up how your scans turn out. It only took me a couple of scans to figure out how to avoid issues, but wanted to point it out. The light just makes it to where some writing won't show up on certain areas if you're not careful. -honestly, the multi-colored pack of the frixion pens suck. There's a major QA issue because they run out at different rates (even with equal use) and dry up fast. I have had luck with the 3 pack of black, red, blue. No issues with that pack, but I kind of wanted the rainbow of colors. They just aren't the same as the "basic" colors. I wanted to share my experience after a couple months of use since that can vary from the first impression. I will update again of anything changes, but I think I've run across any quirks I would have by now.
