Aside from having to wait so long between test, I only had two other gripes about the process. First, the cheek "scrapers" are little pieces of felt(?) on the end of a stick that's inside a tube. Once you're done getting your cell samples, you push the end of the stick through the tube, which releases the felt (or whatever it was). This is actually a tiny bit difficult and I almost thought I'd destroyed one test when I bent the stick while trying to push it through. I got it in the end though.
The second gripe - the return envelope for the test samples is NOT pre-paid. I had to pay $1.13 in postage to send the test back ($1.48 actually because I didn't have the exact amount in stamps). I've already given them $371, the least they could do is pay return postage. The free SMGF test did...!
