Feels like high school project.
I used it on my Epson Xp420. The product needs a good amount of tweaking to specific printer. This is a great idea however did not deliver smooth operation. My printer changed completely from day 1, I installed it, the noise was too loud wasn't able to close my printer because of the tubes were not able to route through the paper outlet. I had to head clean almost ever time I used very unfortunately I was not able to print one print with a decent quality without blurs or missing dots. Customer service is bad I have called for a return , instead of giving the address for return he said he will email in an hour and did not return the email. Anyway the bad part is my printer shut down I had to buy a new printer This happened to me may be its my printer,may be me, may be the product I got was not good benefit of doubt. That's what I think and this is my experience. More than everything they did not refund my money back after returning the product within 30 days.
