I was really relieved to find this ECU for my 2004 Toyota Corolla because the original module had completely failed. The shipping was impressively quick, arriving well ahead of my expectations. When I got the unit, it was already VIN programmed, so it was truly plug-and-play—installation went smoothly without any hiccups. Compared to the dealer’s quote, this repair saved me several hundred dollars, which was a huge relief on my budget. The communication from the seller was clear and helpful, making the whole process straightforward and stress-free. Overall, I’m very happy with the purchase and the professional service provided.
