I would not recommend this product to anyone. It is falsely advertised as a premium product. Along with a inferior product they also use scare tactics to get the sale. Here is an article from another persons negative experience with Trusense. http://www.ripoffreport.com/r/Detech-Firesense/Saukville-Wisconsin-53080/Detech-Firesense-Detech-Techology-Information-about-experience-Saukville-Wisconsin-984550
