Did not work
I have been using this product for years and will continue to do so.  However, the 2nd bottle of this 2-pack I bought was defective.  It was as if they forgot to put the peroxide in it.  It did not "bubble" like it's supposed to and did not clean my contacts. I could not return it since it was past the time period.  I'm just writing this review in hopes that it gets forwarded to the manufacturer.  Again, I like this product, just not one of the bottles I received.
