Bought two of these. One for a customer and one for a demo for a project. First one was great. Worked great two. Second one the antenna was knocked of the clips. I was able to put it back on but not as solid as the first one for the customer. Overall I like these and hopefully will be buying lots more for these projects that I am designing. I would like to talk to someone about my project and what it would take to get these direct from vendor.
