We need put it always in the charging set, if I keep away after the previous call end it may take 15min to next call or I forget to put the handset in charger it will goes to off. And call cut and make call or in same control it make unnecessary calls few times. And voice quality and volume need to give little more. These are the drawbacks and light weight is the useful
Excellent product.
Looks nice and working good. Only cons is battery backup. It is not upto what the feature says.
