The use of the combined solution (cleaning and storage) works well so far and I have no problems continue while wearing my contact lenses.
Compared to my alternative combined solution I have the impression that I need a little longer with lenses after insertion, until I no longer perceive (approx 3-5 minutes). This circumstance submit along with my feeling that I can wear the lenses not as long (about 1-2 hours), leading to the star.
Regardless of the price-performance ratio and the combined solution is very good.
