Review on Printers Printhead Cleaner Cleaning WF 7620 by Paul Barnes

I tried this on four Epson printers with clogged nozzles and got the following results: * Two printers' nozzles refused to clear despite multiple treatments overnight. * A printer was partially erased after several treatments, but there are still gaps in the printouts. * A printer is completely cleaned after one treatment and prints normally. The results depend on how long the printer was jammed. The completely cleaned one was clogged only for a short time. The other three were stuffed for months. UPDATE: When the seller found out about my experience, they offered me a full refund and I accepted. So there is no risk in trying their product.
