First, these refills would not fit into my Revlon eyelash curler. It's a standard metal one-nothing fancy. These refills are way to thick to fit. I used pliers to open up the curler area and to make the refill fit. I rigged it well enough but the refills are way too squishy as in my eye lashes the curler is unable to hold my lashes. A complete waste of time and money. In addition, I ruined my perfectly functioning eye lash curler to try to get the squishy eye lash curler refills to fit. These refills were comparable to using a sponge to curl eyelashes. Ugh!!!!!!!!!!! I did not want to give this product any stars but had to to be able to submit the review!

I liked this product when I first got it, even though 2 of the cables never worked. Soon after another cable quit and today the entire thing won't work. It was great .... when it worked, both months

But the way it ended left me hanging too much! I guess you really have to read all three books in the series to get the full story, I don't know. It was abrupt and just left me rather confused. I did enjoy the characters. They become fairly well-developed through the book. For a lot of the book, I didn't want to put it down I got very involved in the different storylines. There are a few inconsistencies (Jamie talks about being married a month, but Douglas says his cat will be mad because he's been gone 3 weeks....should be more like almost 5 weeks).
