The sound level is too low tones even at maximum, I regret that the use is not intuitive especially for reminders of numbers and internal calls (redial ... it means nothing for those who do not speak English, we must make a long press on the * key int for an internal call) For the rest it is a great product as always for the Philips phones, I hope that this model will have a keyboard that run longer my two previous models (same problem in both cases 5-6 years of life expectancy)
