Q: ...unless you want little wads of yarn roving floating in your fish tank or terrarium. I received a little cup of small, damp, grayish-green balls, but being new to marimos I didn't really know what to look for. Over the course of a week or so in the tank they slowly became more pale and gray as if the color was fading out of it like a dye, and I did a bit of research and realized I'd been swindled. I dissected one and I'm fairly certain it wasn't even any sort of living plant matter, it seriously just looked like a balled up piece of synthetic fibers. They went in the trash and I found some actual lush, green marimos.

A: negative

Q: Would leave less than a one star review if I could. As others have stated happened to them, I got most of the sound out of the left channels only in my car (Using with an iPhone 7). Was fine if I was just listening to podcasts, but music was un-listenable. Waste of money, I;'m now investigating other options. Since it was used in a new (to me) car, it took me a while to determine that the cable was defective, and now I'm outside the return window.

A:
negative
