I was a little worried after reading different reviews, not from this seller but from some others selling the same product. The computer I received was in great shape no complaints there, had a little glitch which was probably of my own making & after making the complaint the seller responded in less than an hour and the problem was resolved. This computer fits my needs for hooking up to industrial engines sometimes in environments not friendly to a regular laptop which has been a problem for me in the past. This laptop also has all the various ports I need, also lots of info online info should a person need
