I've been using this stuff, and I have to say that it is pretty sucky. However, it does do its job, but it gets irritating when you have to filter out sticks and leaves. This brand also isn't sterile, so you should microwave it or somehow sterilize it before using it. It is also very hard to rehydrate it sometimes (It has itty bitty mites and tiny fungus sometimes:-( ) It is one of the cheapest lfs brands there are though, but sticks and leaves probably make its value...
