Bought this in Bangkok, put of curiosity. This is a rare string as it cant be found anywhere else (not even Google~!) After playing for some time, found that it had a cracking sound, not the usual sound that we had with Yonex (ban). It's kinda negative. Repulsion definitely worse than BG66/BG66 Ulti but still playable. However, as the string is very slippery (even more slippery than NBG98), it is very difficult to control in net for tight spinning shot. Definitely, not a string to buy in future. Tested on NS9900 @ 25Lbs Tension: 8 (10 is max) Net: 5 Repulsion: 7 Control: 6 Price: 4
