After a few weeks of use, it got jammed. There is no way to open to spool without breaking it, so I pulled the wire. Then it popped open and the springs popped out. I have since used it as a regular power cable. I wouldn't recommend this product at all unless it is the most inexpensive notebook power cable since the cable itself is durable and has adequate length (not too short, not too long).

I bought this to help reduce my cable clutter when I'm traveling. I'm pretty pleased with the result. It is fairly chunky, the retractor hub is 2 1/4" in diameter and 3/4" thick, but it still takes up less space than my old cable, with less mess. It seems sturdy and well built.

It replaces the laptop AC cable, i.e the cable from the wall AC outlet to the laptop's power transformer. (It doesn't replace the transformer!) At the transformer end, it supports the standard two prong "Figure Eight" connector and includes an adapter for the three prong "Mickey Mouse" connector. These are the two most common laptop power connectors.

This product did not fit my notebook so it is useless to me. The product description did not say that it only fits certain notebooks. Now that it is opened, I cannot return it.

I bought two of these and one worked for about a week, then surprisingly jammed up. It wouldn't come out of the spool. I must have pulled too hard because the whole thing exploded, with the two plastic halves of the spool and the coiled up spring flying across the room. A bit funny and embarrasing in front of a customer... The second one has worked fine.

This is an excellent item for those who travel with their notebook or if you just want to reduce clutter. Stores well in a laptop bag. No problems using this cord outside of the United States with 220v power, however a plug/outlet adapter will needed.
