Used Microsoft Surface Go 2 (Model 1927). Overall, it's in good condition, and I believe it's a good unit with a good battery. ● Set includes the main unit, Type Cover, and AC adapter. ● This is an LTE model with a built-in cellular communication module. You can insert a SIM card and use the internet even when you're on the go or in an environment without Wi-Fi. Communication has been confirmed with a DOCOMO SIM. ● Core m3-8100Y (←More powerful than the Pentium version) 4G LTE Advanced Memory: 8GB SSD: 128GB Windows 11 Pro (Latest 25H2) Screen: 10.5-inch PixelSense Resolution: 1920 x 1280 ● I believe it's generally clean. There are scratches and paint chips on the back. I've included photos of the edges and corners, which are prone to scratches, so please take a look. I am not reusing photos. ● Battery The actual maximum charging capacity is 22,796mWh, which is about 85% of the design capacity of 26,810mWh. The cycle count is also low, at less than 50 cycles. When playing a Full HD video at 50% brightness for 1 hour, the battery went from 100% to 85%, and after 3 hours, it was at 54%. (These are the values at the time of the investigation, and please understand that the battery is a consumable item, so there is no warranty.) ● No screen cracks. The display is also beautiful. There is a hairline scratch outside the display frame. ● MS Office 2021 Pro PLUS is authorized and installed. It's a perpetual license, and there are no additional fees. Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher. (If you would like the product key at the time of installation, I will include it.) ● I have confirmed the following: Web browsing, video viewing, Wi-Fi Speakers Touch operation Camera Facial recognition MicroSD USB-C port ● The Type Cover is also clean. There are faint sticker marks on the palm rest. ● I have thoroughly cleaned both the main unit and the Type Cover, so I think you can use them comfortably. ● To ensure you can use it immediately upon arrival, I have initialized it, completed the initial setup, and confirmed the office activation status.
