I have bought a fitness watch which delivers HR monitor so that saves me putting it on the chest as well. Unit will be sanitised and strap washed before sending. Adhesive on strap perfect as is the working function of the unit. There's only a little marking on the battery cover as the new battery was installed about 2 months ago. Sold on Amazon for an extra 25% or you have save it here and enjoy it all the same!
