Query: Not a good investment

This cable modem stopped working in just 7 monthes. I bought it in February, 2010. It gave me lots of trouble starting in July- I kept having to unplug it, wait 10 or more seconds, and plug it back in to get it to function. Then in August it stopped working altogether. I replaced it with a Motorola Surfboard cable modem, and now I am good to go. I should've spent the extra $20 for the Motorola in the first place.
