Sneak Peek Gender Test

Wondering if anyone has heard of the "sneak peek" test? I read mixed reviews about it and was curious if anyone here has any personal experience with it or knows someone who has. 

For any mamas that are not familiar with the test -->It's an at-home blood test kit that you send in to find out the gender of the baby. 

I do plan on doing genetics testing through my doctor (I believe it's after 10/11 weeks) but I thought the sneak peak test would be fun to try!
