I'm very pleased with the quality and functionality of this outlet for its price, when there are ones costing more than double. It's about the size of a normal GFCI outlet, so it fit into a single gang receptacle, even with a pigtail and two other 12-2 wires inside it with splices. The snap on cover gives it a clean look and was easy to install. So far, I've charged three devices using the USB A and C ports simultaneously, while having an under the counter clock radio plugged in. All devices charged quickly with no intermittent disconnection issues or loss or current. I can't speak to the longevity of the product, but so far I'm impressed and would recommend for the price.
