Negative Positive
Title: A great idea, but...
Review: I bought this in particular because I had a USB device that no longer worked and it appeared to be because of a dirty connection. It really seemed like something an IT person should keep handy. Unfortunately, the cleaning heads are too big to clean a USB "A" cable end - which is what I really needed. If you want to clean the ports in your computer it will do that, but not the adapters themselves.
Is the review positive or negative?
