Excellent price for 10 excellent pens, just be careful not to drop them and damage the tip, because they write badly afterwards

Good pens, they're just a bit strange to write with at first, but once you get used to them they're very nice both in color and in writing

The Xiaomi caught my attention and the large quantity, but I heard a lot of negative comments. We'll see. First impression, it wants you to write absolutely vertically. "Annoying" ...

It writes like a roller, but dries like a ballpoint almost - it will hardly stain you -. Also, it feels like it never runs out. I have written 4 notebooks with one pen and it still has ... now it's my favorite pen. It's a shame it only comes in black

At first I was excited about the writing and comfort, but their tips, when looked at crookedly, stop writing or write intermittently, from the set of 10 pieces not even one finished their ink, they all had some "issues".
I will try the Pilot G2 which are apparently the top in the Gel category.
EDIT: I tried them, much better writing by far, and they also have a button.

Unfortunately, it stops writing properly long before the ink runs out.

The first one I started using, after a while it fell off my desk and shortly after it started acting up (one moment it would write, the next it would stop). Okay, I thought, it must be because of the fall, maybe the tip got damaged and the ballpoint stopped working. But the second one started doing the same thing without having fallen this time.

Definitely for 5 euros they are excellent and have not caused any problems. They don't tire you out too much, the ink dries a little slower compared to bic but there is no issue at all. They will last me a lifetime, 10 of them

Sometimes it doesn't write and then starts again, but overall it is good

It does not have a grip and can be tiring. It writes smoothly and "full" until ... it decides it doesn't want to write anymore without the ink being finished
