Hello, I want to share my appreciation for this product from SquareGlow. Specifically the new one, the Smart Flasher. I run my business in the shop and I’m everywhere around the shop. I do get shipping boxes almost everyday. I rely on SquareGlow to make sure I meet my timelines and ensure operations like print and shipping. So it’s important to me to make sure my packages arrive. The SquareGlow Smart Flasher syncs with door sensor or doorbell button so when the door opens, it sends a alert to my apple watch. If I didn’t have this in place, I would miss my packages for sure. Often, while I’m working I get a call that someone is at the door and I didn’t know. So SquareGlow makes a huge difference as a business owner. I’m really thankful for that product.
