Ohhh cute idea lah, tapi honestly the smoke effect bubbles kadang-kadang a bit gimmicky je and kids get bored after a few minutes, a few of us tried similar ones and ended up going back to the regular bubble wands because they're cheaper and kids still have fun with them! If your little one really into smoke effects and you want something different to try, go ahead lah, but I'd maybe test it out at a friend's place first before spending RM34.90 on the hype.
