Query: WARNING: DO NOT BUY!

This is by far the WORST set of cordless phones we have ever had! After only around 6 monthes the phones started malfunctioning majorly. The charge would not hold more than three minutes after being removed from the charger, the phone would say "UNAVAILABLE" when we tried to answer it, and after hanging up the phone it would start to ring again for no reason. Thankfully, where we purchased the phone they were able to return it no box, no reciept, no problem. Just make sure that if you choose to buy this phone you go to a reputable store with a good return policy.
