Dell Latitude 7450 laptop arrived quickly, in 2 days, as promised from Tekzilla.It basically looks new. Feels solid. Crisp key board. Bright screen. New battery (not OEM). New adapter (not OEM). Booted immediately to Windows personal set up which took just a few minutes to finish.Video is very good. Screen clear, though antiglare mat does give it a slight bluish tinge, however movies and streaming look great. Very fast computer. Boots from sleep very quickly. Internet is excellent. Used for second Zoom station in conference with excellent results on Wifi, conferencing locally, and hardwired Ethernet for overseas. Sound is excellent. Accepted Inswan document camera with ease. Great unit.I will update in a few months about the longevity, but I am very pleased with this refurb unit.Be aware that a refurb means a reconditioned older unit, which this must have been new in 2015 from time stamp. However the replaceable components are new enough and original commercial quality with an updated Windows 10 that it should be fine for at least 3 to 5 years or so. I will monitor to see if the cheaper non-OEM battery and adapter cause problems, and will update my review on those, but even if I have to replace those in a year, at $335 I will still be hundreds cheaper than a new Dell from the manufacturer.I am very pleased. I have had wonderful luck with Dell refurbs in the past either directly from the manufacturer or from Amazon. I'd recommend Tekzilla for a good refurb job.UPDATED 12.15.20  I removed 1 star due to power problem. As another reviewer noted, it began to unexpectedly shut down into sleep mode after about 2 months of using. Sometimes it would do it twice a day, after a bout an hour use even. I never knew when it would suddenly shut down. I updated all drivers, updated the BIOS, checked and changed to "Never" all sleep settings, but it would still unexpectedly shut down into sleep mode. The other reviewer stated (after 20 years as a tech support guy) that it was the knock off battery which was part of the refurb. So, I purchased a Dell battery and charger directly from Dell. After replacing those, the laptop has worked flawlessly. I went in knowing this could happen from the heads up of the other reviewer, so plan on spending another $180 or so for manufacturer battery and charger *if* you have sudden sleep shut downs with ACPI power management shut down messages in BIOS log.
