While I wouldn't call it a miracle product, it seems to increase range slightly and, perhaps more importantly, reduce interference that can come from smartphone radios. Mavic Mini, I probably get a 25% increase in range as well as a lot less app complaints about heavy interference. The Mini operates in the 5.8 GHz ISM band. With the Mavic Pro (Original), the range increase is less pronounced (not that there were any problems from the start). Where it really shines is when I stream the video back over WiFi. This action makes the smartphone's Wi-Fi radio quite busy and causes more communication interference. These reflectors really seem to reduce the impact of this problem. The Mavic Pro uses the 2.4 GHz ISM band. Given the price and the ease of installation, I'd say you can hardly go wrong with this product.
