      Linkit Smart 7688 Duo

      Delivery quick as usual. However the product is flawed and prone to becoming unusable. I am now the proud owner of two of these devices. One failed after several months. The other in two days. Support from manufacturer is nonexistant. Seems the issue is with the flash...........
