they are not being very cost effective the other interesting challenge for Z1 is they mention they don't have the room for these which I understand rear bumpers take up space. However, Have they thought about using a shipping container by boat the real advantage here is that you can buy a good used container for less than $3k and they will drop this off to you. So basically all Z1 would have to do is unload the container they receive at there facility and store the inventory in the container they bought which take up only 10 x 45 ft tops a few parking spaces the container if sound protects the product from the elements and well when all bumpers are sold you can use the container for other storage like used parts body panels and what not to protect them from the elements and worse case scenario you can even sell the container when done. Lastly, you can even rent these containers by the month. So bottom line is I truly feel there is a cheaper way to get at least a few hundred here from the start. I did e-mail TWINZ several months ago to inquire about aiding them in the distribution and they never responded. Regardless they have a great product just need to think this out a little better.
