Great buy and shipping is fast. There is a down and up side of the idem. The good news, it is very bright in very dark areas. It does show where residue of urine and glance images (ghost image) of semen. Down side, it does not clean anything, (such as public toilets with some sort of harmful disease or virus even worse parasites) only clorox handy wipes will help, which is also a great purchase.
