v4ink Bentsai BT-2582P Magenta Ink Cartridge 42ml Solvent Fast Dry Ink Replacement for Handheld Inkjet Printer BT-HH6105B2, BT-HH6105B3, B10

the ink is very dark, it looks nothing like the one in the photo, even when printing on paper, it is almost dark brown. The ink is not high contrast, and not only the yellow, nor is the magenta, and I assumed all the others have low contrast as well. It's a shame, the printer is good, but the inks are terrible and extremely expensive. And to top it off, you can't use inks from other manufacturers because They are locked to be used with their own inks. If you inject it you could damage your device. It is not worth something so expensive for such a cheap result. Apparently the only ink with a high contrast is black (if you print on white surfaces), the other inks do not work the same, white or yellow ink on black surfaces does not have great contrast, you have to strain your eyes to read clearly.
