I picked up mine yesterday and have given it a good test trying to flatten slab table tops. I was not intending to use it as a make-do jointer or a beam planer. I only wanted to flatten large timber slab surfaces that are a bit warped and often chainsaw rough.
I won't go over what Stu already said as the tool does initially look impressive for the money...but...there are a key issues with the tool I bought that render it unsuitable for what I want to use it for (and I'd say even dangerous!)
The in-feed sole
1. Flimsy
2. As flat as the palm of my hand
Flimsy
The front or in-feed sole plate looks rigid, until you apply some pressure to it. It is way too flexible. It flexes all over the place and there's no way that this tool could be accurate with a front sole plate made out of rubber painted to look like metal.

Crap. Really crap! Did I say really crap yet? Set one side of the front and rear soles level (at a 0.5mm cut depth with is another issue). So the reference side is all level...slide your flat edge to the other side and you can drive a truck through the gap. I'd say it's easily a little over 1mm off from one side to the other. That's bad...really bad. Oh...there's no way to adjust this!
Soles line up on right hand side...

Not at all on the left hand side!

The tool looks durable, except for the soles. I reckon one drop with the tool falling on a corner of either sole and it'll break easily. That's just a guess though.
Dust/chip chute
Clogs very easily. Especially if planning across the grain which results in chunkier shavings. It seems that the plastic chip port has an internal lip with catches shavings and blocks it all up very quickly. The only solution is to go very, very slow. Much slower than the cutting action is capable of. I ended up taking it off and that solved the problem. No more blockages. But I shouldn't have to take it off. Simply a dodgy design.

Did try it hooked up to shop vac, but it made no difference. Clogged very regularly.
edit: this clogging happened on 1mm to 0.75mm cuts.
Blade locking mechanism
This part is scary. With the blades triple checked as being secured, after about 45 minuntes of use I noticed the planer seemed to me gouging more than usual on the left hand side (was gouging anyway caused by the sole issues). Inspect the blades and see that one of the blades has slipped out approximately 1mm. The securing bolt is still very tight, but the blade is coming out anyway. Not good. Not good at all. The whole way the blades are secured stuck me as poor from the beginning, and that's the way it turned out to be. Shameful design with potential to be dangerous.

Seem to become clogged very quickly. May add to motor prematurely burning out? Or maybe it won't make a difference.

Initial blade set was hopelessly out of wack! I mean really out. No where near close to set properly. No instructions to adjusting it as the blade seat is supposed to be factory adjusted. Good in theory if the factory does it's job. Adjusting was pretty easy though if you've ever set blades on a jointer or thicknesser.
Add to that the poor infeed sole, and I'd say QA on this tool is poor. You might get lucky and buy a good one, or you might be unlucky and get a dud (like me)
Cutting performance
It cut really nice and smooth! Horribly inaccurate due to the sole issues, but quality of finish in each cut was good.
Stu's review
Stu...maybe your unit didn't have my issues? I can only judge the unit I received. I will be returning it to GMC for my money back. It's no where near not good enough and the blade starting to come loose has potential for serious danger. I'm very dissappointed as I had very high hopes for this tool.
