Too Early to Tell
Too early to tell if it will help my vision, however if the quality is as good as regular BioAstin, it sure can't hurt.

Great quality, but wrong style sent.
I would have given it 5 stars, but they sent me the black when I ordered the blue style. There’s not a huge difference between them and they’re comfortable, so it’s really not a big deal.

Here’s Hoping!
This is my second purchase from Hiink. I haven’t needed to use these cartridges yet, but I am assuming the excellence in quality and performance will be equal to the first set I purchased. If they are not, I will update my review. Meanwhile, I have high hopes!
