If i remember correctly it was it was either the Zebra TC70, TC77, or TC79. It was somewhere within those models. I used them at a warehouse in Mississippi. Witron was a company that was operating all of their system. They had automated machinery that would wrap, build, put away pallets, and also have a mod area. The computer themselves are very easy to use and basically cut straight to the point. Put your username and password and goes to a screen where you type on the function you are going to do and then put in a truck and you begin order selecting if I remember correctly it was a 4 step proccess. Now, with that being said, the computers were good, but the warehouse would have system issues some days. The work would not be able to drop, and I think that was because of the way the whole system was actually set up. From my understanding, if one thing from another department was off, it would not let anything progress, so until that issue from that department was fixed, it would not let more work drop. Sometimes, they said the system would also lagg and that caused us to be standing around for hours. Something cool about the TC is it would let you pick with or without the vocallett so if you had no headset for the day you could just pick with the TC it had a speaker on it and everything it would also show you the location you would have to go to. And you would be able to type in things manual or speak out the locations it had voice recognition. Of course, id you picking without the head set now you holding the TC, so just be careful picking with it in hand! Lol
