Don't buy anything from these people. I purchased a Sierra wireless Air Card from ElectronicsForce.com. No where in the description did they disclose the fact that the devise is obsolete and not compatible with Windows 10. After 10 HOURS of trying to figure out the issue, AT&T figured out the problem. When I called ElectronicsForce.com and spoke with customer service they just referred me to Sierra, and they never answer the phone. They had no interest in helping me. When I called again about retuning the item, they were disrespectful and told me it was my responsibility to make sure the devise is compatible with my carrier. When I told them it's not the carrier, it's the operating system that is outdated they told me I should have called Microsoft. That is the most ridiculous thing I have ever heard! Now they want to charge a 15% restocking fee (and it's a tiny item) and I'll have to pay shipping. After submitted the return request, then they suddenly want to try to help me!? It's too late! I thought I found a new supplier for my company, but I will NEVER buy from them again.
