🎥 HOW TO TEST ACCURATELY: Using a cell phone to measure R F? That won’t work! For accurate results, use a quality R F meter. Don’t have one? Check out our videos to see how it’s done! Here’s how to start: 1. Use a high-quality R F meter. 2. Keep phones and Bluetooth devices in another room to avoid interference. 3. Position yourself about 3 feet from your Wi-Fi router. 4. Test outside the product first, then inside for the difference. 5. Be amazed!
