I buy it again and again, it's the only thing that keeps my eyes hydrated because it keeps the lenses hydrated and in good condition! Also, the "trick" with the indentation for placing the lens case is extremely convenient!!!

I made the switch 3 years ago to this one from Renu that I had been using for 10+ years, I didn't see any difference, it does the same job and it's more economical.

So-so in terms of hydration, it cleans contact lenses well and is suitable for sensitive eyes but it does not hydrate well. My eyes keep drying out.

I have been using optifree express for 15 years. I have tried almost everything because I wanted to replace it due to dryness. In the end, this is the best, I wouldn't change it for anything.

It creates a blur sometimes. It is very good for hydration, even after many hours it doesn't bother you. The closing of the container, which is screw-on, is inconvenient. I would prefer a clip so that it doesn't touch surfaces. Sometimes there seems to be a "soapy" appearance in the liquid due to the transparent container. I bought it because of good reviews, but I am returning to my old one.

I believe it is the best product available. I can wear contact lenses for 17 hours without my eyes drying out. I can even sleep for 3 hours without them drying out.
