Could someone tell me more about these please, what exactly are they for? Have no idea what they are but have seen them in a few set ups.
Hi GC, it's known as the Twinstar based on a the original innovator product. The one that you refer to is an imitation product.

Most people here are outright skeptics which is a good thing. I not sold on it but it would increase your O2 levels ( a little) which is almost never a bad thing IMHO.
