PROBLEM: After going through 2 sets of these I have thrown them in the garbage. We used all 4 lenses and could not make out what was on them. I can find nothing sharp when looking at my screen. Total waste of money. Bought another brand this weekend to replace these. This is a piece of junk that would be OK if they were 5 bucks. Not recommended. One star for Amazon Prime. As long as you get free shipping, go ahead & try it out. No hassle.

SOLUTION: Bad review

PROBLEM: I bought this as a gift for my father who has been complaining about how hard it is to find his favorite brand in stores, so I'm happy that Amazon.com had them. The bottles were wrapped properly and look fresh. Thank you!

SOLUTION: Good Review

PROBLEM: My dog loves this product and it seems to work. However the last 5 orders I've received contain an ingredient other than what is listed. This would be 4 Star if there wasn't food color in this. :( The previous order had no color. I will not buy again. Amazon needs to update their labeling. Otherwise, it's a good product. :) Thanks!

SOLUTION:
Good Review
