CISS spills ink during transportation as corks are made of rubber which shrinks and leads to ink being poured out.
Has 100 % airproof sealing in shipping position thanks to silicone stubs. Possibility of printer transportation with pre-installed and filled CISS  for large distances.
Made from thermoplastic, not steady to the wear and tear, which leads to ink being poured out in the printer and to high probability of breakage of printing head.

Made from silicone, has sufficient length, which allows to prolong the warranty term.
Chips are soldered to the cartridges, which does not allow to swap a chip with one CISS or another. Frequently requires an original cartridge for CISS functioning.
Chips are made at factories, not requiring original cartridge to work. Located on the black plate, which allows to take off or set in a few seconds with one CISS or another.
Very often soldered together, in case of finding holes it is necessary to change all CISS without possibility of repair. There is no possibility to change connected cartridges, the repair-prevention holes are absent in the cartridge.
Made from high-quality plastic, can be easily disassembled and  interchanged, which allows to swap from one model to another or replace the damaged cartridge.
CISS installing requires physical changes in a printer (sawing off of partitions, making holes), which 100% deprives the customer of warranty.
CISS installing is very simple and takes up 5 - 10 minutes. Installing does not change the construction of the printer, which allows to save original printer warranty.
