Pros
Pro It can provide very fast connection
Given that your computer has a USB 3.0 port and your broadband allows for fast connection, this adapter will not limit your internet speed at all. The maximum data transfer theoretically is 640 Mbps, which is way beyond the connection speed most people have. It's also dual-band, which may help alleviate Wi-Fi congestion as long as your computer supports a 5 GHz network.
Pro The internet connection it provides is very stable
Two large antennas make this adapter very good at receiving Wi-Fi behind walls, doors, and between floors. This is especially true when it comes to the long-wave 2.4 GHz signal that the majority of devices support. Generally, you don't have to worry about your connection suddenly breaking up.
Pro The wireless signal reception is very reliable
This adapter has an antenna that helps it maintain a reliable connection to a Wi-Fi network even if your router is in another room or floor, or just pretty far away.
Pro The connection speed is decent
As long as your computer supports the latest wireless protocol, 802.11ac, you will get a pretty fast connection. The fact that this is a dual-band adapter also helps with alleviating some of the Wi-Fi congestion that arises when too many devices are connected to a network (but you have to make sure that your computer has 5 GHz network support).
Cons
Con It's very inconvenient to carry around
The adapter itself is quite bulky, it weighs a little over 0.5 lbs. It also has two long antennae sticking out, so it takes quite a lot of space in the bag.
Con It may not work on the latest OS's
The adapter may not work right out of the box on newer operating systems: Windows 8 and 10, as well the latest macOS versions because of driver issues.
Con There are faster adapters for newer computers
This adapter only supports the USB 2.0 standard, which is significantly (more than 10 times) slower than the USB 3.0 in data transfer. If you have a newer computer with a USB 3.0 port, you could get a much faster connection by getting a compatible adapter.
Con It's bulky
This adapter has a large antenna, which makes it less convenient to carry around and use outside of home or office.
Con Poor support of newer OS's
If you use Windows 10, there could be some driver issues you'll have to solve before using this adapter. You can contact Edimax Tech Support if you're having problems with installation.
