I had an infrared thermometer is a different brand, the measures were not at all accurate. I then decided to invest in this thermometer and I was not disappointed at all, the product is simple to use and accurate. Luckily, I had the thermometer just a week before my daughter grabs roseola, I was glad to be able to control its temperature constant without the need to undress or wake up (it did me peaks 40C). In conclusion, I highly recommend this product.
