I don't see how they could at all. I am surprised they didn't put the Krieg system in there and call it a "metal rod biscuit" or some other baloney.

I think it is important to realize that in some cases these magazines buy these tests, contract these tests, and in other situations probably just buy the copy outright. Mssr. Self would know the protocols on that.
But what gets me, is the way they test the machines. Once again, we are looking for the end all, do all type machine. Where is that machine? With a tip of the hat to the shop bound fellas that do this, I don't really care how well it works in the quiet confines of my shop with all the proper room, clamping equipment, and time I need to get the machine squared away.
I'd bet dollars to doughnuts that if you tried out those tools again in the hands of someone that drives up the the job to trim an house and build a couple of laundry cabs or a built in clothes hamper, he will take the Domino first, and the biscuit machine second.
As for strength of joints... great for those who want to exert several hundred pounds of pressure on wood working efforts. How many magazine/ casual/professionals have seen enough failures of any of those systems to be of concern.
I think too for the lowly biscuit, it is important to remember that they only test with one biscuit in the joint. Two biscuits give a tremendous gain in a joint, and unless it is 3/4" material, everyone I know uses two now.
I am not a big proponent of biscuits, but until I can justify the cost of the Domino (quit taking those damn roof repairs, Robert....) the biscuit joiner will stay with me. I will try to remember that I have NEVER had a joint that was joined with biscuits fail.
Who knows - since my joints don't come apart... there may NEVER be a Domino in the future for me. I actually be more interested in the Rotex Super MF 1000 Platinum Stealth Wood Transformer and Satellite Tracking tool. They sell it as a "sander" (yeah - right!) down at WoodCraft.
