Looks good

Tiny, poor quality allen bolts

Brand new stem. Using a 5 nM torque wrench, carefully, one of the heads on the steer tube tightener bolts stripped.
I would not buy another one for this reason. They are a painted bolt. A 5M stainless would have been a much better design.
I will have to hacksaw the stem off and buy something else. Very weak!!

Very light, very secure. Reasonable price compared to ultralights. Three bolts are probably better than two?

The bolts are garbage. M4 bolts that corrode isn't a good idea.

The stem looks good and the design is unique. It's a little trickier to get the bars on/off but it isn't impossible. The finish of the stem is top notch, the only problem is the bolts. I switched them out for stainless ones.

Light
Stiff

Difficult to install

I've never noticed such a difference in changing a stem! Once swapping my Oval stem for this I noticed a change in handling. It tracked a little more 'stiff' because this stem is simply very strong. It's also very light for what it is. My only complaint is that you'll probably have to un-tape your drop bars a bit and I had some trouble putting it on my flat-topped handlebars. But you only have to do it once.
