We have done Sequencing.com tests on 2 of our family members so far. And have had great experiences with them. We had a snafu or 2 with billing and updates but Sequencing.com's customer support was amazing. I recommend signing up for the 1yr update plan.
There will always be times when an email is lost or overlooked in life but they've been really good about being fair and willing to work to resolve issues. I don't want anything for free but fairness and understanding goes a long way.
Unfortunately, I bought 2 DNA kits from another company and have yet to hear anything back from them after 14 mo & paying $5**, so we have had other bad experiences with other companies to be able to compare. I recommend Sequencing.com
