Got mine tonight and did an initial setup. I have a few thoughts and my final setup configuration below.
I am very impressed with the overall quality of the lift. The packaging is great and the double casters are plenty beefy. I was wondering why they cost $100 and now I get it.
First problem for me was a missing nut for the rear subframe bolt. I had to run to Home Depot to get a M10x1.5 nut and washer. I am sure it was just an oversight but people should be aware of it in case they need to know what to buy.

After that was sorted out, I put it together and it was pretty simple.
I set up the horizontal alignment to make for easy engagement and actually used the wrong mount hole (8) in the adapter plate and had it in position 8 in the beginning. I didn't notice this and went ahead and lifted the bike. The bike was leaning forward but the front wheel was off the ground. I didn't really care for it so I pulled it down and tried again. I found my mistakes and decided to set it up in the correct mount hole (7 )but left the horizontal alignment for easy engagement. The lift slid right in but when I raised it, this happened:

The rear is off the ground but the front wheel touches. Back to the drawing board...
I decided to put it as suggested in mount point location 7 and make sure the horizontal was set up as suggested (3.125). This made it very difficult to engage and I actually scratched (pretty slight) my frame trying to lift and wriggle it in. Here you can see how off the pins are and the result:

Just a slight lean towards the back and I had to push the lift handle down quite a bit to get it to begin engaging. I could get about two fingers under the front tire in this configuration. It still isn't right.
I walked away for a while to relax and read the posts here for ideas and with a clear mind went back out to play with it.
I played with the horizontal adjustment and made some progress at 3.237. It was a little tight with engagement but it did work and got the wheels off the ground.
Looks good in the pics but it is still a little tough to engage (not like in the video in the OP) and you have to lower the lift handle quite a bit to get it to start to engage. I can only get about 2 fingers under the front tire.
###Final Configuration###
I went back to vertical position 8 and started over on the horizontal adjustments. Here is what I ended up with:

Perfect engagement with the lift arm all the way up and it slides right in as I stand the bike up.

Plenty high now. I can get about the width of 4 fingers under the front tire and about 6 under the rear.
Now I can swing it 180 degrees and ride it out. So much better than it was before. I also tried getting on the bike while it was on the lift. I am about 250lbs and it felt very solid. I have no worries rolling the bike around on this thing. Once the safety pin is engaged, you can pretty much grab the bike anywhere to swing/move it around the garage. Very cool stuff.
