Along with that, they make brief mention in Store News for EverythingHerePlus.com: FireRepeater-800 PRO gets a glowing review from IT Enquirer, of an excellent review which discusses the FireRepeater-800 PRO Four Port. An excerpt:
In contrast to its competitors, Unibrain’s FireRepeater-800 PRO has a wall mounting bracket to secure the unit in place, and the ability to screw-lock your FireWire cables in place. I would recommend the Unibrain FireRepeater-800 PRO to anyone wanting to connect more devices to his computer than he can daisy-chain, and up to a longer distance than is possible without a repeater device.
Given their breadth of FireWire knowledge and glowing customer reviews, you'd be hard pressed to find a better place to purchase FireWire products.
