The product works well. It measures fire very easily and quickly. I tried and it measures right. Packed very well. The seller sent it very fast. I finally got rid of waiting to measure fire for a long time. If you have a patient or I will surely recommend it for your child. You can measure fire in 1 second while you sleep
