Summary: I read the reviews b4 i bought this item and it does work. I normally have a weak signal and computer would run like crap because of it, but now my computer runs better and the signal strength is the best i've seen. No complaints so far it does the job just fine, i would buy again if this one broke for some reason.
Summary: Great product. Will solve your problem if you are just a bit out of reach of your wi-fi hotspot. Exponentially increases your range and signal strength. I highly recommend if you've been having spotty internet coverage lately.
Summary: I think that the previous users were probably not using this product with Leopard. The installer lets you choose between 10.3 (Panther?) and 10.4 (Tiger), but there is no driver for Leopard. I tried the 10.4 driver, but it really doesn't work. Hawking Technology acknowledges that the driver locks up your Mac when you reboot or when the computer goes to sleep. There is a 3rd insidious way that the driver locks up the computer that I don't recall right now.
Summary: This thing is great, it pulls in everything within at least a quarter mile. Many times stronger than the antenna in my Macbook Pro. It comes with good documentation and a CD with excellent software that shows real time signal strength and link quality. It comes in a well padded box 8" x 6" x 5" that you could pack in your suitcase. Compatible with OS 10.3, 10.4 and 10.5 Exceeded my expectations.
Summary: Recently I was travelling around seven states in the US. As you will understand that when your on holidays it is hard to stay connected to your emails, and alternatives like my iPhone would cost too much to use outside the UK. I knew this Hawkings Antenna device was available for PC's but I could not purchase a MAC version anywhere in the UK. So I thought I would take a chance on this product and purchase it while travelling. Taking a chance really paid off.
