Product Review (submitted on June 1, 2011):
These are some good, standard magnets at a reasonable price. Their strength is all around average, and can be used for a variety of things. Whether these magnets are good or not kind of depends on what you are using them for. If you are just simply demonstrating how magnetism works, then these magnets are perfect. But more demanding tasks, (I used them for a science project) they may fall short in the strength department.
