Have the kit now extensively tested, (4Monate-ca. 50h), and can recommend it only. The only flaws that I have found are, - The signs in the midst of the club is gone (I do not care) - One of the bands around the handle fraying something out (I've seen worse) - The balls are all already in the garbage (broken into 2 parts)
Otherwise the bat objection are free, still excited beautiful, and it's still fun.
Conclusion: If you want to invest more money to do it. However, I am fully satisfied with the bat. To replace the balls Sport 2000 Speedertube Mixpack are second to none.
