WOW,these people are awesome. I emailed them that I was having problems aligning the blades (which was a pain in the rear), I got an email from them this morning as a reply and they are sending me a new V2.0 head for my MR6. WOW- I was not expecting that and am more than happy. I WILL be ordering more goodies from this company. Thier customer service is above reproach.
