Is this Traditional or Modern age?

Hi, im looking for your opinion on this club,



Will this teach me the highly effective art of JiuJitsu, or is this the modern JiuJitsu, (ive been warned to stay away, as it is 'watered down' and not as effective. Is this true? Is the modern Jiujitsu not as effective?



Thanks
