Nightingales Home Health Services and Physiotherapy Clinic - Battery back up is less its less than committed in user manula.

I purchased Philips simply go machine from Nightingales Home Health Services and Physiotherapy Clinic. As per the user manual minimum battery back up should come *.** mins when used at no * in pulse mode. Its hardly coming for only * hr ** mins to max * hr ** mins. They are absolutely unprofessional. They had given wrong invoice in the beginning and they are taking forever to give a battery replacement. Absolutely tortoise speed of service. Don't buy simply go from Philips brand and don't buy anything from nightingales. There service is poor to the core. All they are interested is in selling afterwards. Very difficult to catch this people.
