What an actual user from Amazon.com has to say :

... this little wonder works great on my Vostro 1500, despite the bad reviews. I live in a podunk little town, and I got six very strong Digital and HD signals, and that was even without the use of the external antenna included, wich I would not use anyhow, due to it's magnetic base.
