Hello I have the dexcom g4 that goes with the bomb and I agree with all of you the Seven Plus lasted more and was smaller and could extend more than 15 days and the battery lasted almost 2 years.I have had to throw because they no longer sell sensors and have given me the Animas Pump lives and saved the screen.I have refused to pay so much money for the sensors and 6 months ago I do not buy unless someone wants to sell them at most 50e each or if someone has an idea of how to get them cheaper.I'm fed up with Novalab to do business with us.
