Sneak peek test

Hey ladies. Wondering if anyone has done the sneak peek test and if it was accurate or not? Apparently it is 99% accurate. I thought I wanted to do a gender reveal party and now I don't really feel like organizing another party when I'll have a baby shower. Plus I am just so excited to know and it would suck to wait another 2 and half months if I could know next week. I'm already getting an elective ultrasound at 13 weeks since I haven't seen the baby since 6-7 but they won't do gender that early and I don't want another unnecessary ultrasound really. Let me know what you think and thanks in advance.
