Purchased in 2022. It was tested (video) and still works. This model is unique with a touch pad, colored screen and rechargeable battery. Please note, the back of the calculator has black pen ink marks near the label (photos) and the on button sometimes sticks. If you press down and move it around in circles gently it will work again. This calculator does NOT have an off button (do not be deceived by “off key”) since it turns off by itself after a few minutes. Dimensions: 3.4 in W x 0.6 in H x 7.5 in L Weight: 250 g
