Very good. Works as represented.
Great. The online instructions are clear, and the plankton sparkled and glowed from the very first night.
Love these glowing little things. When I first got my order mine were dead as they didn�t glow. I reached out via email and they were happy to replace them. My new ones glow very bright at night! Very cool to have around the home. Thank you.
Quick delivery, well conditioned package�
My 6th-grade daughter picked a really neat science project-- Bioluminescence: Investigating Glow-in-the-Dark Dinoflagellates. We ordered from a company that was listed in the middle school students' resource guide, Carolina Biological Supply. The three specimens arrived with VERY little activity even after allowing the three separate specimens to "recover" their bioluminescence after shipping. After two weeks elapsed, we observed a few sparse glowing flickers, and we started to worry that the science fair project would be a bust. Luckily, my 3td grader found an ad for PyroDinos, and their specimen literally saved the day. I am a native New Yorker and a natural skeptic. So, I was thrilled to see that PyroDino's live specimens actually glow as advertised. You do not have to squint to see the glow. The glow is bright, obvious, and intense.
