Considering aligners instead of metal braces, anyone try AlignerCo?

I’m leaning toward clear aligners because I’d rather not have metal braces as an adult, but Invisalign is way out of my budget where I live. While comparing options I came across ALIGNERCO, their price is much lower, and the package already includes whitening and retainers. From what I’ve read, it seems suitable for mild to moderate cases. Has anyone used AlignerCo while skipping braces? I’m curious if the results held up long-term or if braces ended up being worth the money in the end
