Query: Did not work with Samsung Slash M310

Delivery of product was timely. Charger appears to official Samsung OEM. Could not get it to work. Did not seem to make connection when plugged in. If I wiggle it and press hard into phone socket, I can get it to power on the phone but it still won't charge. I am not returning it because the postage that I would be responsible for would be more than I paid to begin with. Ordered same product from OEM 4 Less. Worked perfectly!
