I bought 6 pieces to carry children's toys. At first they were just wrapped in bubble wrap and without any information or instructions. At first everyone thought they were infrared thermometers. When I told them how they were, everyone was grateful for the reader's qualities. The display is easy to read, bright and versatile. My husband will probably use it on his bike as he is an avid cyclist. I love that everyone will now have this in their glove box - you never know when you might need a tire pressure gauge, especially in the winter months.
