Nice and compact. Gains wifi signal very well despite wall between the wifi router and the gadget. I have a dual band router but eventhough the product says it is dual band I could connect only at 2.4 Gz. I need to experiment a bit on the 5 Gz band. Easy to install. Just plug it in and enter the wifi password and you are good to go (Windows 10). The antenna is good though it is not very tight.
