This little dude saves me a lot of money! I know it's expensive at first but it is well worth it! It works every time!IMPORTANT HELP: My chip resetter wasn't working but I have had mine for almost a year and this was the first time I have ever had this problem. I hooked it up to my phone charger USB cord for about 5 minutes, then tried it again on my maintenance box and it worked perfectly. Another thing to try: If your light stays red and you have the pins and contacts aligned, try to move it just a tad bit while on the contacts as sometimes it will be off just a little hair and will cause it not to work. Hope this helps someone!

Came as described and worked as required to clean printer ink.

Easy to use. Worth every penny! Saves money not having to replace a maintenance box all the time.

Why did you pick this product vs others?:I thought it would be a good buy but turned out to be wasted money. Worked 1 time now so I get is the red light. So I'm back to buying waste boxes.

Definitely a money and time saver. I no longer have to purchase maintenance box or wait for them to be delivered. Product was easy to use and works perfect once you line the pins up correctly. Worth the purchase

Works perfect to reset my waste box for the Epson ET8550

Overall the resetter works as indicated. The maintenance box shows empty when I use it. The only issue I'm personally having is that when I use the box I reset, I get more ink output causing splotches and I'm unable to run a satisfactory print test. I run the cleaning 2-3 times and it does not help. I use the regular maintenance box and my ink output is back to normal. The end result is not what I expected.

Using with Et-8550. Seems to work well
