Q: This case is made of VERY cheap plastic. It broke while I was trying to get it on my ipod. The plastic breaks easily and can be taken off. DO NOT BUY!!!!!

Q: I use these to replace the filters on our air quality monitor. They have done a good job and are just what we needed at half the price that is typically charged. Thanks. :-)

Q: If you are going to sell products like this please have a website so consumers can contact the manufacturer in addition to sending emailed questions. I will look for other books as I was not able get anything from it that i needed and paid a premium for. There should be an option on amazon or in their advertising of other titles if anyone is interested. Amazon just doesn't seem interested at all in customer feedback. How sad.

A:
Bad review
