Great value for the money I also have the grs standard ball vise I ordered about thw same time and at this point have used both about the same amount. To summarize:. Is the grs better quality? Yes. Is this reflected in the price? Not even close!. Compared to the standard grs, 1 being terrible 10 being no observable difference.. weight : 10/10, performance: 9.5/10, finish and feeling: 8/10 ( diff not worse). Rubber base : 9.9/10. Size and shape 10/10, attachments 9/10. smoothness of adjustment 10/10. Rotation : 7.5/10.... I would say domt waste your money on grs this is good enough for a pro any day in my opinion. Idk maybe I got a good one but basically it's worth the money in this case you get way more value per dollar. Only get grs if you don't care about money or not working your own hrs is great product but so is this one.
