i use it seldom cos i find it veryhot around the waist in the summer in HK. but i was glad i did use it one time. i was walking on Stanley street in central, very crowded & it ground was not flat, i tripped & fell. lucky my girl (who's 2.5yr & weighs 14kgs), didn't get hurt, cos i had both arms on her back & her bump was protected by the hippychick seat. altho i had a hairline fracture on my knee. if it weren't for the hippychikc seat, she would've fell thru my arms & hit her bump & spine.
