Seems to be equal to quality and construction to any other units I have purchased. Only noticeable difference being this one is constructed more of plastic than others, which upside is the head is lighter in weight, time will tell if that is a problem or not. Output, operation, and features are equal and in some aspects such as wireless connectivity, surpass other brand names. Can't comment on durability as of yet since it's only been in operation for little less than a month, but so far flawless operation
