At first had trouble. The instructions that came with it would not reset my printer. I emailed the seller and about 24 hours later I received another set of instructions that worked on my printer. The price for 4 is great I now have a good supply of back ups. I have and do recommend this. It was an easy install of the ink tray, good quality and fit perfectly. It is compatible with several printers.

Easy process

I only used it once, I don’t know how the other 3 keys are supplied to work because I did not see any counting bit it work perfectly. It was super easy, my only issue is that I had to download the driver and restart the pc to make everything work out but the process itself is pretty easy. The printer work like new and the installation was easy too.

Fits perfectly in the Epson ET-2720 and reset software worked!

The waste ink pad replacement fit perfectly in the Epson ET-2720 and looked to be identical to the original that needed replacing. The reset software they provide also worked without any issue.

Not everything included

It says it comes with program to reset the printer an all the information that came with the tanks takes you to sites that want you to buy the key to unlock. These were purchased with the idea everything you needed came with it.
