Example Input: This is an excellent product and I have been using these pads for many years. There are other more expensive models, but they come in a very flimsy plastic packaging which does not protect them from moisture or damage. My only complaint about this box holder is that you must take the entire top of it out to open it.
Example Output: Good Review

Example Output: Bad review

Example Input: I've been doing some online work in Firefox for awhile and noticed that my internet use was going up.
