It's ok....
I decided to try this because during allergy season, which for me is all summer through the end of fall, I tend to have a lot of protein deposits on my lenses and was only getting a weeks wear out of them instead of two weeks.  This was suggested to me so I gave it a try.  So it does help a little bit, my lenses stayed cleaner a bit longer but I still have to replace after one week.  Had no problems using it, have my contacts soaking for 8 hours each night and never a bit of burning when I put them on.  And I know it says no need to rub your lenses but, yes, you very likely DO need to rub them clean.  Anybody with deposit issues needs to rub their lenses clean!  After taking them out of the solution in the morning they have a film on them, from the broken down protein deposits presumably.  A quick rub with saline and they are clear and ready to wear.  Don't know that I'll purchase again since it didn't make much difference for me.
