Nice torch projecting good infra-red light. Small unit, but aluminium housing appears well made. Would have given 5 stars however, there were no instructions on battery requirement type and when opening cap at end it is easy to mistake as needing a 'coin shape' type battery, which is incorrect. Rang cust serv enquiries and courteous & helpful lady said she had received a recent customer call for the same problem !! Should have at least some instructions within box - nothing. As it turned out with the operators help - I turned the open ended torch upside down and then suddenly a plastic barrel 'battery housing' (to fit 3 x AAA batteries) fell out, which then solved the confusion. So not just me but others have had the same problem - Remedy - Please place some instructions within delivery box. Thanks
