LCD Monitor Touchscreen, 12.1" Touchscreen Monitor POS System for Restaurant Bar Point of Sale Cashier Coffee Store PC Touchscreen Display VGA USB

Purchased this in July 2020 for my shop. Noticed a gap at bottom of the screen but kept it because I needed it for my lone POS system. Six months later, and the touchscreen sensitivity seems to be haywire...I touch one item and it a different items comes on the screen. I have to now resort to using the mouse to click through purchases. It's a real pain until I purchase another better touchscreen monitor. I feel robbed because this cost over $100....
