Ok but....

It ok but it's not as described. Seller claims this to be a 520nm laser but in fact it is a range from 510-532nm as indicated on the laser. It doesn't perform anywhere near what is claimed. In daylight it's visible about 30 feet maybe. It's quite bright and visible at night or dim light areas but I cannot recommend this laser. This is the 2 nd of 3 lasers from this seller who is being very receptive to customers. Bait and switch again from this seller. They are not to be trusted. I also have a blue laser that is not as advertised from this seller. 

Buyer beware
