This is the one she really wanted as one of her friends owns this particular style and loved it - it was easy to use and worked great. Our daughter was familiar with it and knew it worked. We were able to get ours at our local Lowe's - which they had 6 at the time. Two days later they were OUT as it seems to be a popular college dorm item for people to buy. Check your local Lowe's first but if you can't find one - the link above goes to Amazon and you can order it for about the same price.
