This unit works great so far. It arrived damaged which is a disappointment. When you spend money on something brand new, it would be nice to receive it in mint condition and leave the disappointment of dings to the future when you make them by your own fault. While a general "covers several units" set of instructions may seem cost effective to the company, it's NOT helpful to the customer. Had quite a bit of confusion on some steps. They really should minimize customer frustration by having unit specific instructions.
