These shafts are absolutely marvelous, lost the count of the number of 180s I've hit with these. Excellent. Five times the value for money in terms of the quality it adds to the throw. However, these shafts have got extremely short lifetime - I play darts maybe maximum 30 minutes on average every day and they break approximately 3 weeks after. That is very dissapointing. Other shafts break after the same amount of time as well, but providing you pay about a quarter or a fifth for other shafts it's all right, but paying £5-£8 every few days makes it not worth it really to use these shafts all the time. But in terms of the quality, if your throw is similar to the Power's throw, I'm sure in a few days you will score more 180s than ever before!
