I bought it a long time ago and used it many, many times. In fact, I use this product every time I open my computer for recovery or repair. The small ports are very handy for getting into almost every crevice to pick up the dust balls that live in most computers. I have a Beam central vacuum in my office and it fits perfectly. A few things I'd like to see is that the clear plastic tube should be longer! This allows you to leave a really big hose on the floor and not have to hold both the vacuum handle and the hose with the micro nozzle. Another thing I don't like about this product and why is 4 stars instead of 3 is that the little spikes don't stay in place! They stick together but contract like vacuum cleaner hoses but keep falling off when cleaning which is very annoying.
