Q: I bought these shoes for my daughter and my daughter loved it as they look good in rainbow colors but these shoes broke in less than 5 months. I never expected this from SKETCHERS. Really disappointed. Not worth buying.

A: negative

Q: It seems like nobody makes a good mechanical pencil anymore. As with other mechanical pencils I have tried recently, the lead on this pencil fails to automatically advance within a very short time in operation. This kind of defeats the purpose of having a mechanical pencil. Time to revert to the old yellow #2?

A:
negative
