Does anyone know about this? According to the google translator, they found problem in grip so they are recalling ZFII series.
Check out http://www.yonex.co.jp/badminton/news/2016/06/1605191500.html. This is only for certain batches of JP coded VTZF2 rackets.
And TW/CH coded racquets as well. http://yonex.cn/company/news/index/20160524-C http://www.yonex.com.tw/news.php?index=461&c1=2 Apparently the rest aren't affected, hence I decided not to share it, so as to not let people freak the f*ck out, and run to the streets calling mayday. According to the news, the grip MAY not conform to the rest of the frame and may loosen during use. It's been ongoing for a month and a half already. For once SP seems like a safe choice, rofl.
