For over 15 years I wear soft contact lenses (monthly lenses) and so have tried all conventional care products rather - of even more expensive to cheap. And I am convinced that this one is the best! No annoying rub, scratch or the like. Simply enter in the evening, the lenses in the container and in the morning take out clean! I see no deposits and wear my lenses usually 40-50 days without the slightest problem! For other care products (with Scratch) I often had to replace the lens after 3 weeks because of the comfort had become so bad! One need not specially another means for wetting / Rinse off - easy to use! In my opinion, here it is worthwhile to spend a little more! However, since each bottle is a lens case about to put into perspective the price difference compared to some other favorable product! Absolute buy recommendation!
