I'll never understand how Next disparagers get their numbers. The screenshot [1] clearly shows $21.67 per month for 30 months ($650.10).
Next is effectively 0% installment loan for buying a new device with the (admittedly terrible) option of terminating the contract and returning the device for a new Next contract.
