I bought a Jambox at 50% off. Seemed like a great deal until I received it. Sure enough, it was an open box item, either used or refurbished, and surprise-surprise, did not work.
I contacted their customer service and their response was essentially, "What? That's crazy. We'll look into it and get back to you in 5-7 days." Never heard anything back.
I ended up returning it to the manufacturer.
I will never use halfoffdepot.com again! It's not really half off if it's not new. I could have bought a working item for the same price on Craig's List.
