Did exactly what it says, arrived on time, worked straight out of the box.

Delivered on time and has been used a few times with out any problems. Will report back if there are any. Looks a really good buy

Quick delivery, and it's easy to use. I'm glad I bought it.

This is awesome. I noticed my printer was refusing to print telling me a cartridge was empty when it was actually 1/3 to 1/2 full! problem solved and I'm now getting 100% from the cartridges, also able to refill with aftermarket inks so it's​ a win-win.

I’ve tried this on several cartridges. It works a treat on colour cartridges, but does not work on black cartridges.Update:- my octopus now renders all cartridges useless. I was going to send it back but I’m just out of the return period. Not happy.

a bit expensive but worth it as now i can refill to my hearts content

the only way i have found to refill chipped brother cartridges that works.

Impressive
