I think this is an example of design failing. This is a redundant single-application product that can be thrown on the heap of other salad-spinners.
The mechanism for creating centrifugal force to remove water from the lettuce, while aiming to simplify the design aesthetically and cost-effectively, is laughable because it’s completely inappropriate for its context. (Swing this thing around me head indoors? Are you kidding me?) The method may amuse designers, but it compromises the product.
I dry lettuce using either a stainless steel sieve or a towel, both of which can be used for multiple purposes.
Designs like this irk me profoundly because they’re a glaring example of how designers work in direct cross purpose with the need to reduce, reuse, recycle, and, frankly, reapply materials. This does nothing but feed superfluous consumerism.
