Good glycaemic control in type 1 diabetic patients prevents the onset and progression of chronic complications. Continuous Glucose Monitoring (CGM) systems help patients improve glycaemic control by providing real-time glucose levels, glycaemic tendency, glycaemic swing rate and by alerting the patient when the glucose value read by the sensor reaches a predefined threshold of hyper or hypoglycaemia.~Several CGM systems are available and they have different characteristics that could influence patients' quality of life and glycaemic control.~In this randomized cross over study investigators will compare 2 different CGM systems: Eversense implantable sensor (Senseonics, Germantown, MD, USA) and the standard transcutaneous sensor Dexcom G5 (Dexcom, San Diego, CA, USA). Investigators will evaluate sensors' accuracy, impact on quality of life and efficacy in optimizing glycaemic control.~Patients will use Dexcom G5 or Eversense for three months, respectively, in a randomized order. Accuracy will be evaluated comparing sensors values with capillary blood glucose at home.~Quality of life will be assessed at the beginning and at the end of each three-month period through validated questionnaires to underline differences in different sensors use.~Time spent in target (70-180 mg/dl), in hypoglycamiea and hyperglycemia will be evaluated with both sensors to assess differences in glycaemic control induced by different alarm system and by the presence of predictive alarms
