I'm the Retail Security officer, stand at the door checking the slips to ensure that items on the slip are corresponding with items in the bag. Your Application has helped me a lot. I love when customers approached me for electronics items to describe for them and thanks a lot. I have to continue with learning because it is wide and good. I'm from South Africa 🇿🇦. KEEP UP THE GOOD WORK. THANKS AGAIN.

★★★★☆ Dustin Wise · Jun 1, 2024

It's a pretty informal app really my fave thing on it is the AI but there a couple of things that could be added to make it even cooler like a laser diode driver and the Mw Nm of some drivers laser diodes that write at whatever x speed
