Early Gender Tests?

Has anyone used Peekaboo or SneakPeek gender tests at home and got an accurate result?

My long distance friend and I are pregnant together and due within a week of each other. We’ve been talking about including each other in our gender announcements and thought it would be fun to both take the test, but have the results sent to each other and somehow announce that way. We just want to make sure we’re getting an accurate test before dropping $70 on one!

I know we could wait for the ultrasound, but not even ultrasounds are 100% accurate (I was supposed to be a boy until my mom was 35 weeks with me)

TIA!!
