We do not send parts which require opening of our products, as opening the case would subject the warranty to be voided, as there are components in them which are either dangerous or would render the device unuseable if care is not taken.
I am not sure what concerns you have, exactly, of sending the units in to the U.S., but you may want to contact our repair department to see if there are ways to mititgate them.
I have the same problems too. you do not expect me to start shipping the Einstein from Nigeria to the states, if the warranty goes void, it will be my own doing and not yours. the cost for shipping the item back to the state is twice the cost for 2 new Einstein so i need the replacement to put it in order.thanks
