Not easy to use - Firefield In-Chamber Red Laser Brass Boresight

I find this borsight laser lacking in the ease of use category for one reason....the batteries have to be removed to turn it off. Which leads to another problem, storage of the unit and the batteries. I have another laser boresight that has a carry case, a rechargeable battery, a usb charger and the unit turns on when the bolt is closed....all for only a few dollars more. I'll never purchase another product from this manufacturer.
