I've been in an office environment with this product for a week, and am looking to see how long the tip will last before failing. The rubber is starting to pull away, showing some signs now of cracking, I only use the tool occasionally but it should not be failing so soon. Too bad cause it's perfect ergonomically otherwise. A very high defect rate on mine makes me think that's just the nature of the beast. Would love if they could re-design it.

Ex Output:
Bad review

This book was the worst one I have ever read. It should be required reading for anybody in politics. Do not support this trash book. He calls people who don't agree with him liars and racists. That's just gross. If we really care about other people, why are there lies that would take away from people's rights. He's the definition of a politician. The only person he has is himself to blame if he's so stupid to believe these stories. He seems like an intelligent, kind man.

This is very heavy and takes a while to dry. Even though you put it in the dryer with high heat, as instructed (on low), it'll take more time than others I've used that are not so heavy. The size of this product was great but I had to return it, no fault on Amazon's part. It just wasn't what my husband wanted.

Ex Output:
Good Review
