As you know, we're getting some parts produced in China. One of them is the feet for calculators we are selling. We have ordered samples from a producer, and when satisfied then we ordered a big lot.
When we have received it, after paying the producer and 100€ in import duties, we see that the producer has "improved" the product by rounding the edges. Nice, but completely wrong for our requirements, as can be seen in the enclosed picture. The whole shipment to the dustbin! We have ordered a new production batch but will take some time to arrive.
