While the price is high, I think it's justified by the fact that you can seamlessly erase the ink

The 2nd major issue is that it tends to smudge ink, especially other Frixion pen ink

The yellow ink is very very bright, as expected, pink is the dullest, and orange has the most pigment

These highlighters have a friction style eraser which erases the highlighter gel ink very well and completely These are great for highlighting only small areas like school books or small areas in novels but not for larger uses like highlighting discontinued medications on MARs used in the medical field.

Some inks will smear (and obviously you'll have a problem if you try to erase highlighting over pencil), and Some papers accept erasure better than others

The ink is bright & vibrant just like any other highliter & they erase really well.

It works beautifully on standard copy paper, but for what I really wanted to use it for (book paper) the eraser has almost no effect other than slightly smearing the ink underneath.

If you erase the ink it still stays on the paper, just it's invisible

I know some review discuss these not erasing completely, but here is a fun fact, the ink is heat sensitive.

Leaving a book in a car in the sun provides enough heat to erase the ink, which might be good for some but is bad for most.

only problem was it then not only erased the highlighting, it also took the ink out of the text and smeared it all over the page.

Make sure to wait until the ink is dry before erasing the highlight.

(Ink runs out quickly but worth it)

As long as you wait a few seconds for the ink to dry, the friction of the eraser completely removes the ink's color

It is worthwhile to experiment with different types of erasers, but again, different erasers will give different results with different inks and papers.- The ink itself (at least the yellow ink) isn't very bright

In a few seconds the ink disappears like magic!Also, if you later want your marks to reappear, just pop the page or book into the freezer for a little while

These will smear even dried ink as they are obviously a little wet

The ink is faint and hard to see compared to other brands I've used.

It does not highlight bright as advertised or erase the little highlighter ink it left on the textbook.

Tried the yellow ones out, but they smeared the ink on my pages when I used the highlighter

They smart the ink of the book when you try to erase them

The only issue I had with this product was that the erasers did smudge the ink on the page if you are annotating a textbook, for example, but I recently discovered a way around this--simply erasing with a pencil eraser does the job

Most of the time there is barely enough ink to see even a faint highlight

Faint ink.

The highlighter comes back and it smudges the printed ink on the page.

Shaking them to restart it would work, but would leak ink everywhere and quickly dry up again

Highlighted ink may smear if erased too soon, unlike other highlighters that use a "color canceling" highlighter to erase

But the highlight didn't completely erase and the ink underneath smeared.

Third, when you erase your highlighting, the ink is not permanently gone

These highlighters have a friction style eraser which erases the highlighter gel ink very well and completely These are great for highlighting only small areas like school books or small areas in novels but not for larger uses like highlighting discontinued medications on MARs used in the medical field.

smears textbook ink.

doesn't erase completely and smudges the ink in text books when you try to erase it.

In general, though, using the eraser doesn't produce perfect results, especially if you're marking up a book that was printed with cheap ink or on cheap paper

With certain papers, the erasing mechanism can leave some marks or smudge the ink, but I've only had this happen with documents which were printed using an inkjet printer

If the highlighter didn't smear the ink, the ink would smear when I tried to erase the highlighter

they're bright and the ink is smooth and when you erase it you can't tell that it was ever there

I guess it does erase the highlight considering it tears the paper after smudging the ink around
