We went into the week before Christmas with no backorders in the US. However, worldwide there was a huge Christmas demand, something we had not seen since the downturn of 2007 and did not expect and were not ready for. Worldwide they are literally hundreds of pumps behind and they trickle in, we actually have fewer backorders than most of Europe at this point so they are focusing on catching up in Europe. Unfortunately, I don't have good news, I would suggest your best bet, if you know you want these pumps is to place an order and reserve a place in line, we optimistically expect to be caught up and have these pumps back in stock for immediate shipping at the end of March, it could be longer. Until then, there will be a wait for 6105, 6205 and 6305 and waveboxes. It sucks, but there is not much that can be done about it beyond what we are doing, stepping up production and trying to catch up.
