i have several lasers and have bought more recently and waiting for delivery, the site what i last purchased before these dosn't say anywhere which polarity , even after e-mailing them they havn't replied [ laserpointerpro ] GrrrrrrrrHow can we be sure of the correct orientation in cases of lasers that didn't come with documentation? Is there a general rule that we could follow?
so.......... as its a cheap green dss id say with a spring its a - what goes in 1st
i am also NOW going to put in a book what polarity for them, with pictures lol
and maybe a white sticker [ small ] on to say which way as well...
it isnt good if you paid £100 plus for a laser and it dosn't say what way you put batteries.....it's ok if you have just ONE laser but i have 3 now, and 2 more coming, at least Sanwu [ where these are coming from] tell you what polarity........clap hands.
But it is easy im sure for a manufacturer to just put - or + on a laser for god sake.. come on guys!
