These were purchased for use by our service technicians.  Hope they last a long time.  They have nice displays and good size hard drives and RAM.  They start up very quickly and I had no problem in swapping them over to log onto our corporate network instead of the default workgroup, since they do come with Windows 10 Pro.  We like the fact that they still have a 9-pin serial port, something that has been dropped from most laptops.  We have older equipment that we still need to communicate with over a serial port and have found that many of the USB to serial converters are not very good.  Only certain chip-sets work and it is much nicer to have a built-in port.  I have connected to our network via both wired Ethernet and WiFi with no issues.  The monitors are wide screen and bright.  I went ahead and purchased car chargers for them but have not tested them yet.I must say, I originally took one star off of the rating because I purchased two PC's at the same time and one of them was completely DOA out of the box.  I added the star back after receiving another unit that is working.  Since I had a second unit, I tried it's battery and even without a battery and it just would not turn on at all.  I contacted the company through Amazon and they did call me back and tried to troubleshoot the problem.. They were very nice and without taking much time, apologized for the trouble and agreed to send me a new unit, which they did.  As of March 3rd, I have finished loading all the software needed on the two machines and have tested the networking, both wired and wireless, the serial ports and USB ports.  All seem to be OK.  Will get them into the hands of our servicemen soon and see what they think of them.
