I purchased this No Touch Forehead Thermometer by #BiuBuy for my sister for Christmas. She owns her own pilates studio and she lives in NYC. In order to protect her clients as well as her employees and herself, she checks everyone who is at the doorway to her studio. The noncontact thermometers oft Wed n are bulky. What I love about this is its unique way of plugging it into the bottom of a cellphone so the likeliness of losing it or misplacing it is highly unlikely. One less thing to stuff into a pocket or keep track of, as you keep it attached to your phone. I also love that despite it's small size it is highly accurate. At $42.49 it right in line with some of the larger, bulkier no touch thermometers on the market. I highly recommend getting this as a gift or for yourself especially if you are a business owner or need a gift for one.
