Don't waste your money. They could triple the amplification again and that would not make it a bit better. Remote devices don't have amplification. So the net result will be you will be able to see the AP (router) and it will have a good signal. Only problem is you will not be able to communicate back to it. If you amp you laptop signal, battery life will suffer. If it sounds to good to be true... then it is!

The title of the article says Long-Range, yet after reading the whole article, there's no mention of an actual range in meters or feet..

higher transmit powers do improve range when you have a good wifi radio on the router which is sensitive enough to work with very weak signals.

Also wifi connect rate is not uniform, the upload rate and download rate are determined separately so higher transmit powers can improve download throughput even if the range is not improved due to a client transmit power limitation.

Over the past few years transmit powers have increased significantly even though very few router companies do not advertise the transmit power.

from the days of the wrt54g's it was common to see 15-30mw transmit power, but today, your average/ mid range router will have a transmit power of 600mw, and some of the higher end ones, eg look at the fccid's of a few netgear routers (they don't advertise their transmit power on their site but they are pretty high), you will see around 600-700mw on their mid-upper mid range routers, and around 900-1000mw (the legal limit set by the FCC) for their high end routers.

Most users focus on download speeds more than upload (and confirmation packets take very little bandwidth). By boosting the transmit power, you can not only ensure that any range limitation in your network is is due to the client and not the router, but for what ever range you have, on average, you will have higher download speeds.

Not entirely. Improving the receive path on the router (either by higher power or better antennas) will yield better performance at the client even if the device doesn't have amplified transmit power. The improved router will be able to hear the device better (via its improved receive path). Though something like "3x improved power" won't necessarily correlate to 3x the range or performance for a device.

If you improve the receiver sensitivity, you can improve the range of your network without changing the transmit power on the devices.
