買激光電筒或激光筆(20點)

no no no!!

$50 below you can't get a high power for indicate the star or burning stuff !!

if you want to indicate the star,you have to buy 532nm(green),>100mW,
about($250),

if you just want to burning stuff,you can choice >50mW-<150mW for green laser.

if you like to play tract with people,just $15 for toy shop get a weak laser - 5mW 635nm Red Laser.

i got a 700mW green laser in Ap Liu Street,

remember to bring a laser power meter to check the output power of the laser pointer,so labels is scame!!

for almost toy shop,you can get it,just for joking with those laser(5mW)

旺角女人街（通菜街）應該有得賣。一年前我行經那裡，見過激光筆，即演講時用那種。

小心使用，不要照自己和別人的眼睛。
