Steam Deck OLED 512GB - Purchased online. Selling because it didn't suit me. - Reset to factory settings. - Battery life: 100% - Operation confirmed. - Everything in the pictures is included. - No pets, non-smoker. The A button has a slightly sticky feel since it arrived at my home. There are no issues with the operation. I mostly used it connected to a controller, so I haven't touched the main unit much.
