Have any of you used 23andme for zygosity?

My dudes are obviously fraternal, so we didn't need to do any testing to confirm. But we did do the 23andme kits this  year just out of interest for health information (the FDA does not currently let them give you any advice about your health, but you can still view raw genetic data and download it to use at other websites that offer some health insight). But, you can compare your kids against each other and see how much genetic data they share. Identical twins show up as having identical genetic data, while fraternal twins share close to 50% (like any other siblings). 23andme kits run around $100 per person, so it comes out to a little more than some zygosity testing companies and a little less than others - but since you get access to things like information on your potential ancestry and possibly health info if you are study-savvy, it might be a cool option for some of you who want to pursue testing anyway so I thought I'd share
