Does anybody know if the 532nm green modules from dealextreme are any good. For example this one 100mW 532nm Green Laser Module (3V 11.9mm) - Free Shipping - DealExtreme
Any idea if they are IR filtered (doubt it)? The prices sound to good to be true and you know what they say, if it sounds to good to be true it probably is.
