Bought 2 from cloud tail on lightning deal. for 330rs its the best value for money racket which may can feel slightly heavier then gr303 but it is isometric head so larger sweet spot and it is perfect for beginner. am playing badminton for 2 years but i just bought this to use it for practice session. there are peoples always ask.. which is best gr303 or zr100l? in a simple formula the gr303 can look better when priced equal but when on deals and if you found zr100l cheaper then go for it, you wont be disappointed. some players may like heavier rackets too those players prefer zr100 over gr303 even when priced equal.
