ROCKETBOOKCloud Cards - Eco-Friendly Reusable Index Note Cards with 1 Pilot FriXion ColorStick Pen & 1 Microfiber Cloth Included - Single Set of 40

I have used index cards extensively. Having reusable cards is a great win.

Work as advertised, but too thin for my liking, getting them in and out of the pack frays card edges. With an erasable by heat pen any sturdy cards would work the same, but the app makes these more handy if you need to scan the notes into one pdf/image

Really useful for note taking

As other reviews have shown there are consistent marks/notches on the long edge of each card. Assuming this is a result of the manufacturing/cutting process, it is most prominent when they are stacked together. Also, I had to go through and pull/brush the loose parts of these chips away.Having said this, there is no detriment to the operation and function of the cards and everything works as expected.Rocketbook make some great products that I have used for years. I just feel that the end product quality in this case doesn’t quite meet the mark.

I waited months for these to come in to stock and they look like old stock - the dots are hardly visible and I have just noticed that these are damaged at the top even though they came in a sealed box. Very disappointed

The pen is nice, the ink flows onto the card in a satisfying manner and looks good (ie legible), after about 5 or so seconds you can erase your notes cleanly with the eraser at the end of the pen, my only (for me) real gripe is actually about the pen, the Co. has been too cheap to include a clip on the pen cap, a real point of ire for me, if had of included one this pen would have been pretty much the best, there are plenty of third party pens out there that do the same job as this pen with clips, but to buy a pen just bc this Co. has been so tight rankles. Anyway, this is my only real (for me, it may not bother you) problem with this purchase. The cards are a little too thin to expect them to last, individually, for much more than a couple of semesters (but obviously, I don’t know this for sure yet, I could be wrong). You get 40 cards in the pack, so plenty there. I’m sorry, I haven’t used the online capability yet, so can’t give an opinion.Overall, I’m very pleased with my purchase, as I have been with others from Rocketbook, such as the A5/A4 sized erasable books I have used for a long period.
