So I received a Promax 350 helmet for Christmas, decided to do the right thing an read the instructions first for a change, couldn't believe my eyes when the diagram for the battery holder in the manual didn't match the helmet??? Double checked the model number etc. Thought this was a typical poor set of instructions (common to almost all tools we buy these days) and was ready to head back to the supplier for a refund when I thought of Googling my question and couldn't believe I found this website straight away and my problem was solved. Great informative website. Just a suggestion; updating the instructions for other purchasers would be a good idea!! Regards David SDate: 26-12-2021David Stalker
