Firstly, I'm still a novice where AI upscalers are concerned. But I've done enough research to see the value in this one.

Secondly, I did reach out to the owner using the support email he provided in his responses to comments here but never heard back. I did that about a month before I purchased it. I wanted to make sure this upscales large enough for my needs. I do want to add that about 20% of the emails I send go to spam. So maybe he never saw it. But I like to be transparent in all things.

Lastly, in spite of not hearing back I went ahead with the purchase about 2 weeks ago anyway. Why? Because it's an amazing value to have lifetime access to a true AI upscaler and it works the way they say.

I've used it a bit since purchasing and it's worked exactly as it should. It can upscale to double your original or 4X your original. You choose the radial button. I need a very specific output size in my work so I start with an image a quarter that size and upscale 400%.

Some notes:
The maximum this will go to is 16,000px on either side. Just an FYI. Many folks don't need to go that big. That's 53.33" x 53.33" in 300DPI if you're printing. PRETTY BIG. I only need a 10,800 long side but I did test larger files and they are definitely capped at 16,000px

Your starting image cannot exceed 10MB. Mine do not. But when I was playing with the larger images it stopped me on one that was 10.2MB

The maximum batch size you can do at one time is currently 8. I'm Okay with that. I sometimes have 10 and just split them.

The output image shows 72DPI when I inspect it (in case that matters to anyone) but from the research I've done this is just semantics as long as the pixels are correct? Again, I'm still learning and providing all my notes in case it helps anyone looking to buy this. The pixels are definitely correct and the image works perfectly for my needs. I do run it through a python script in an automation process I have which changes the actual DPI to 300 since all the required pixels ARE there. Maybe this is how all upscalers work?

I'd like to repeat that this is an AMAZING value. If you need to regularly upscale images and have them upscale correctly there are other options out there. But they all cost a heck of a lot more and are subscription based. This product provides exactly what I need for my daily work and will pay for itself in just 6 months. At that point The subscription based product would leave me with an ongoing monthly bill. Consider me a very happy customer!
