550X Dominator Super Combo. I'm not a big fan of unboxing videos. That having been said Align makes a great kit! I did want folks that haven't had the opportunity to open one to see how it arrives and STRESS the fact while the head and tail are pre-assembled they MUST be COMPLETELY disassembled and EVERY screw going into metal must be thread locked. I also wanted to run through my unboxing routine and manual routine...I think it sets the builder up for success with this kit or any other. Lastly I wanted to go over a couple things like the Anaerobic Retainer that I found confusing in the past. Hope you find the video helpful and enjoy!
