These come in strips of 8, just like most PCR tubes, and can take a little effort to twist apart. The caps snap in place easily enough. I tried several while testing two centrifuges and they held up nicely. They seem as well made as other PCR tubes I've handled. I can't speak to whether the price is good relative to some standard, but I can say that there's a lot of them (which is good, because they tend to get used up quickly). Mine came in a pack roughly the size of a tissue box. Each set of 8 strips (i.e. 64 tubes) was in its own sealed bag.

There are no surprises here, these tubes are exactly as described. They come packaged a dozen strips in a tamper-evident sealed bag, with 10 such bags in a box. The tubes are solidly built, clear and with clear lids. The lids close easily and stay closed, and yet can open and close repeatedly without becoming loose. Although connected in a strip of 8 they can be snipped apart easily if singles or a smaller chain are desired. Be sure to check the size information: they are .2 ml, which is very very small -- albeit perfect for certain processes.

Let me be clear upfront, I am not a professional user of these tubes so don't have the experience to pick the more detailed nuances someone else may expect.I have a small hobby lab at home where these will be used. Usual things, microscopes, petri dishes etc. It started as a side issue to my aquarium hobby but has taken a life of its own. So when I saw these and a centrifuge on Amazon, I decided to give it a try too.These fit into the standard PCR holder that my centrifuge came with. It takes 4 strips of 8 tubes. The tubes stay joined together in this mode. Or I can separate them individually an put them in pairs in the centrifuge.They seal up well. I've had no leaks and are easy to use. From a hobby perspective, they do everything they claim and I find them useful in my "homeLab" mixed with my microscopy hobby. I am not however qualified to give a professional opinion.

Quality feel, easy to close (given that they are 0.2 ml tubes), and packed in stacks of 12 in individual baggies that make safe handling a lot easier than loose strips in a box.
