Yes, that's the one. It is 1.8 ohm per the spec so I guess it's not defective. But with a 24V supply this will draw 24/1.8 = 13.33A
When I drive this from a 24V 10A supply, the voltage measured across the power supply terminals drops to around 16.5V. So the heated bed is drawing around 16.5/1.8 = 9.2A and the power supply is current limited. It's not good to run a power supply like this.
To actually drive this safely at 24V it seems I will need a 15A minimum supply.

This one? http://www.ebay.com/itm/Heated-Bed-Kit-for-Ultimaker-Reprap-3d-Printers-MK2-PCB-Aluminium-plate-/161157442118?pt=LH_DefaultDomain_0&hash=item2585bb6a46
I believe they are shipping the third version.
I have the 2nd version with the thinner 2mm alum. It measures 1.9 (room temp) - 2.0+ (60C) ohms. There is enough drop in the wiring to measure 23v at the connector.
