Review: Love Rocketbook!!! Will NEVER use a paper notebook again. - I love my Rocketbook notebooks! I’ve been using Rocketbook notebooks since they came out and have not looked back. I religiously scan my notes using the app and then wipe it clean - it’s almost a zen moment as I clean off the old to prepare for the new. I use for work notes and now that I’ve gone back to school, I am using Rocketbook there as well. I like color coding my days with a different color as the frixon pens come in an assortment of colors. Finding them in a .05 finepoint was a game changer. Give it a try!
Review: Lifelong customer now! - I was so excited to get this and rightly so! I love my rocketbook matrix! It does what it says it does! As a math educator, it's really helpful to work out all types of math exercises and then scan it into the cloud so I'm not having paper all over the place (I keep all of my math work lol). As an entrepreneur, I can also then use it for any other note-taking, brainstorming or writing I have to do, and either erase that or scan it. I really am stoked for this, and will probably now be able to stop hoarding notebooks and looseleaf! I just got the Panda Planner and am considering a mini notebook as well. A few notes: 1) It's a little tricky to use if you're left-handed though as the ink takes approx 15 sec to dry so will smudge until then 2) using the pen station, or adhesive pen holder, is super helpful as you can only use certain types of pens with rocketbooks and you don't want to lose it; 3) get a mini spray bottle that mists and has a cap or otherwise 'closes' so it's easier to wipe down (sometimes I spray the paper, and sometimes I spray the cloth if it's a small space that I need to erase) and won't accidentally spray in your bag; 4) the rubber/silicone tip is an eraser, so it's good for small and quick adjustments where you don't want to use the cloth, just be careful as you kind of have to wipe/rub the residue away in order to write over the spot again; 5) the frixion fineliner marker pens don't show up that well for me (may be the settings in the app), but it might be better to use the colored frixion gel ink pens instead of the marker pens if you use different colors in your work; 6) definitely get a separate set of the frixion pens with refills with this purchase as the ink in the pen provided really does go fast; 7) there isn't a bookmark or placeholder, so you might want to tie a thin piece of string or ribbon around the binding spirals to keep your place if that's important to you; 8) you might want to get a small supply bag to keep the spray bottle and cloth (and perhaps the pen(s)) together; and 9) I have found it helpful to use a clipboard to write on when not at my desk or table, as the rocketbook is durable but not super sturdy. I mean, you CAN use it without the clipboard w/o a problem, but if you prefer to write on a hard surface often, then a clipboard will help. Hope this is helpful!

## Questions & Answers

**Q: Does this come in executive size also?**
A: As of October 2020, no. It was just released in the first half of 2020 so it’s relatively new. Several customers have commented on their website requesting an executive size; so perhaps they will release one in the future.

**Q: Has anyone. tried to use a compass to do math problems? I am worried that a traditional compass will poke holes in the rocketbook.**
A: I've never tried it, but you are correct to suspect that a traditional compass "might" damage the surface of the Rocketbook.  If the damage is significant enough, the ink will settle into the small holes and won't wipe off.  However, as long as you are using Frixion Pens, heat would erase it.  

You could test it on one page to see if the surface is damaged, and if so, how much.   Even if there is damage, it might not affect what you are doing.  There are a couple of pages in the front that would be perfect for a test.  One test is worth a thousand opinions!

If you need to protect the surface, what I would do it to put a small piece of clear packing tape down where the compass point will go.  Packing tape is thicker, so as long as you don't press down too hard the compass point should not penetrate it.  You can still see the lines in the Rocketbook page to locate the point accurately.  

By the way, I'm a retired engineer, so I've done exactly what you are doing on a variety of vellums and drawing surfaces.  Never on my Rocketbook though!

**Q: Does this come with the spiral across the top?  A spiral on the side gets in the way in my opinion.**
A: The spiral is on the side/spine like a book.

**Q: Are there plain white pages included?  I need room to illustrate math problems without lines or grids in the background.**
A: one lined page, the rest are gridded.

### ⭐⭐⭐⭐⭐ Great tool for lesson planning
*by T***F on December 28, 2020*

I purchased this after seeing a TicTok video of a Rocketbook in use. I was sold without looking up anything else. Then I asked a co-teacher if she had ever heard of them and she said, "i have 3." When she showed me hers with classnotes in it I had to get one. I ordered the Matrix and received it quickly and immediately was enamoured with the quailty and ease of use. The first thing I did was use the grid sheets to lay out a map for a game. I erased the map, which is very easy with the included cloth and a bit of water, and then used it to design my semester exams for my IPC and physics classes. After scanning them and sending them to their respective google folders, I again erased the book and used it to write out my physics exam and answer key. Every time the pages looked as new as the day I opened it after cleaning. I did have one mishap with the Rocketbook but consider it a lesson learned. I left a small cup of water on my desk and bumped it, spilling the contents under my keyboard where i couldn't see it. the water ran to the edge of my rocketbook and wicked up the pages it touched ruining the work i had there but had not yet saved. I cleaned it up and redid my work, and I learned to 1) keep your rocketbook dry because the ink will run; and 2) save your work when you are finished. Rocketbooks are designed to be reused not to be permanent (unless you buy the single use rocketbook). In all, a fantastic product that I have had for less than a month and already used a ton, and I will buy a few more, for personal use, and to give out as incentives for my students.
