Q. I have an Audio-Technica AT-LP120-USB turntable and would like to upgrade the cartridge. My budget is $100-$200.

A. The eyeglass ...Read more

Q. We are having an issue with our Bose Wave radio/CD system. It has an add-on that provides an additional three CD capability. The slot in the radio itself is playing the CD properly, but the three CD add-on unit has begun to make spinning, sputtering, skipping noises. After a period of time it seems the CD begins to play normally.
In checking...Read more

I often have to add air to my bike tires, so the idea of getting a $20 inflator I could use with my Ryobi battery system was very attractive. Yesterday I went to my local Home Depot and saw that the $20 inflator was for inflating air mattresses. The high-pressure inflator was $...Read more
