Functional and inexpensive, usually at the expense of reducing the cost of materials, the handle of the D1702K is thin, non-slip, and difficult to move if it is filled with a little more water. The lid is a little not tightly sealed, and the lid opening switch is designed on the lid, but the lid itself is not scald-proof, so it is easy to burn your fingers when you open the lid.
 
Fortunately, Grad is also the first brand in China to launch a one-year free replacement for quality problems, which has helped it greatly increase its market share.
