Not to good - Caldwell Platinum Series, G3 Electronic Hearing Protection

I returned these as the fit and finish was sub standard. They we flimsy and seemed fragile. They needed too many batteries and in order to put them in I thought I was going to break it so I never installed the batteries to check function, that is why they received 2 stars not 1. Spend a few more bucks get Leight impact pro, I did and happy with leight
