Top tier product. This pad replacement came with the instructions on how to fix my Epson printed that I've converted into sublimation. I never knew it had a drip container and I literally thought I was going to have to spend a lot of money trying to fix it. I looked up some videos and saw i needed a replacement kit. THis is it is I have an epson 4800 the video walk through with the paper was EASY, to put it in was even easier. Highly recommend.

Perfect

Software is a bit clunky to use but worked perfectly (not to mention a huge cost savings!)

They do have a key to resolve it. Make sure you can connect your computer to your printer.

The customer service is great. They answer your email within 2 hours. The product itself is great too! Comes with two ink pads, gloves, etc. just like what they are advertised. They have instructions and if you have any questions, you CAN contact them. Sadly, my computer couldn’t connect to the printer so I couldn’t use the key they gave me to resolve the problem. I got the printer second hand, wanted to fix the issue, but in order to fix it, we need a cable to connect the computer and the printer. It’s weird that we found two different software (same purpose), but one can connect, the other one (the one on the instructions with this product) can’t. I confirmed with them that we do need a cable. I asked my printer seller about the cable and googled about it, both said the printer doesn’t come with a cable. But when I emailed them (this product) about my issues, they said it should come with a cable to connect. So I don’t know the answer about the cable but what I know is that I either but a cable myself or buy a separate key on their website and hopefully it works. If you don’t know your key, you can email them and ask about it. They then will send you another instructions (another method I assume). It’s a really long key, so if you can connect your computer to the printer, I’m sure you can use the key that comes with the product. It’s just a little bit of a slow process, but at least you know now and you can easily fix it in the future. :) In case you want to know my printer model, it’s ET-4800. These are just my opinions, I hope you can fix yours without any issues! :)
