Additional Glasses? (1 Viewer)

I've got the samsung 55ES7100 which came with 4 glasses and I'm thinking about buying 4 more, in case I have guests. The glasses I have are the SSG-4100GB and use a battery. They seem comfortable and the picture is fine.
Are there better glasses, image wise, or are they all pretty much the same? If they're all the same, than these will do. They cost $18 and change on Amazon, which seems ok.

get the same / model of glasses as you currently have.

Thanks. I was leaning that way.
