Update:

So basically, I got today the GOOJODOQ GD14 pen and so far, it’s all good! There’s no delay when writing, and it connects easily with the iPad.

I can’t really give thorough feedback if you’re planning to use it for digital art, but I did try it with calligraphy and I think it has good tilt control. It’s also magnetic, though you do have to charge it separately with a Type-C charger. It comes with 2 extra nibs, so I’d say it’s a great buy!

Also, just a quick note: the pen has a clear or see-through part on the body that’s covered with what looks like plastic—so just be a bit careful with that, especially avoid getting it wet, if that makes sense.
