Reviews from owners
Mostly positive Owners who moved up from Penguin II units say the Blizzard NXT cools faster and moves more air, and several note it no longer starts with a bang. Complaints are fan noise on high, the extra height over a Penguin, and some early-unit failures, though one owner reports about three trouble-free years since replacing two warranty failures.
