Pros Works great as a repeater or portable AP.
Cons The configuration scripts look like they were cobbled together from two separate programs.
The basic configuration is attractive and easy. The advanced configuration seems to be taken from an older product.
Summary Buy it. It's great to have with you to boost WiFi signals where they aren't very reliable or buy it as your house's main AP. The range is great and the price is right.
Pros Simple to configure, simple to use, provides 4 useful modes of operation
Cons Poor documentation provided
Summary It does what it promises and does it well. It can be used as router, AP, repeater and as wifi adapter. All these options are easily configured through the device's own web page. Even though it's very small (62mm W x17mm H x 86mm D), it provides a good range with a normal coverage you would expect from a device with an internal antenna. Its strength is its portability, and it even brings its own transportation bag.
On the negative side, the documentation provided (user's manual) is very poor, and you have to figure out for yourself how to use any of the advanced configuration options.
Overall, this product deserves a high rating - it has an attractive price, and its portability together with the its different modes of operation makes this device a good companion for your network needs when you're on the move.
