Not sure. They don't look like any of mine. I am confused as to why the question. Are you buying them on like ebay or something, or do you already have them and want to know if you should use them. If you already own them, go ahead and use them. If you are getting a really good deal on them, I would say go for it reguardless of the brand. Most manufacturers do not make their own stuff but instead buy it overseas and have their name printed on it. The overseas manufacturer often makes the same equipment for different brand names. Sometimes there are only slight differences just to give a different outward appearance but other times the only difference is the name (or lack of a name).
