Query: There's a class action lawsuit for this series of models

I bought the base and two handsets 2 yrs ago, and one of the handset completely stopped working after 1.5 yrs. After a year, we replaced the rechargable battery in every handsets, but one of the handsets started loosing it's power very quickly (we charge for 6 hrs and it lasted for 10 minutes), and then stopped working.There's an ongoing class action lawsuit against the series KXTG and KXTC in NJ, and the law firm encourages every consumer, regardless of state, who had any problems with these models to fill out a questionaire at their website (they only ask for your name, email address, state, and comment). http://www.sheller.com/Practice.asp?PracticeID=140
