Logitech Headsets H340

<p>I recently bought FOUR Logitech h340 Heasets from Esquire (as a dealer). I returned THREE as they did not want to work with Win 7 & Win 10. Esquire after taking TWO LONG WEEKS agreed to replace them, BUT here is the problem:</p> <p> </p> <p>Esquire exspects me to PAY FOR COURIERS on each and every occation, and takes NO responsibility as a supplier. Therfore it is impossible to make any money on these kind of sales, as my courier fees exceeds any profit margins.</p> <p> </p> <p>The FOURTH unit has now also broken down, and therefore I would have to send this single unit back, AND I'm expected to pay for couriers for this also.. </p> <p> </p> <p>I've explained to Esquire that there is enough documentation on the Internet that these units are problomatic, in fact I know other large companies has dropped these models due to the problems experienced with them.</p> <p> </p> <p>However, Esquire refuses to refund me, but simoply offers a replacment of the same **** units.</p>
