A compact box addresses this customer need.

an early version to try
We will test a prototype of the smaller box.
prototype 用来学习和修改，不应当作已验证的量产成品。iteration
a change made after testing
Our next iteration will have a wider lid.
iteration 要说明根据什么改了哪里；不是单纯重复制作同样东西。3 · Rehearse, then change the details

We can repeat the opening test before approving the design.
