Why my string is so easily to be broken?

I have this same problem when I played badminton. I guess we are too strong lol. If this is becoming too irritating, maybe you can invest in a better racket with higher quality string. And if it breaks, well, you restring it instead of buying another new one.

Well i have played badminton for years, including national championships so i think i can give you a few advices on this: It's not normal that the strings break so often, unless you're using them in a very demanding daily basis like competitions etc, which i suppose it's not the case. Probably the rackets you've bought are not the best quality. I would suggest you to buy Yonex or Pro Kenex, Carlton...those brands are good in general. Their strings are nice. And if they break, which will happen sooner or later, all you have to do is going to a sports shop that is specialised in tennis etc and tell them to put new strings in it, with the proper tension. That way it will assure a way better performance.

Prehaps you can try replace it with metal strings but the effect is a bit werid prehaps you would wanna try it yea .

i've been playing badminton going for over 6 years and i have not heard of broken strings due to the kind of racket used. . . by the way, how do the strings break? i mean, do they break in the center? if that's the case then we can safely assume the strings break because of regular pressure when you always smash and the ball hits the same spot frequently, if not always. . . you also mentioned that you only string your racket at 20 lbs. . i think that's quite low, considering i have mine done at 29-30 lbs. . . so, the only remaining thing i can think of as the reason for your breaking strings is the string itself. . . change the kind of string you're using. . .for myself, i use BG65Ti. . . titanium coated strings are stronger. . .the string you're using i'm guessing is too thin and not appropriate for smashing. . .

Oh my goodness, I never new badminton was a competitive sport. It was always a game we played in the backyard at picnics. We would buy cheap badminton sets at a Pharmacy Store of all places. We never thought about the quality of the equipment. It only had to last 1 day. We just picked the color we liked best. My suggestion would be to be careful in storing it even in a case. Is anything pushed up against it when you store it or do you leave in in the car to heat up in the sun and cool down at night. I do not know- do the strings or racket material expand or contract with changes in temp or humidity?
