I've had the cobbs uv light for a year now, used it today, actually I use it pretty much everyday, it was worth the cost. No need to make the room dark, it helps, but it is not necessary.
LOL lary i have to hand it to you, you do not miss a beat. You must have mikeyradar. any way those lights are prob weak but just buy like ten of them and duct tape them together and you will have a very powerfull uv light and still prob cost way less than a pro model.
Larry you should know that I have a few of your units for us to use, what I am looking for is some I can give to repeat pet problem customers.
I get alot of " I think the dog/ cat has stained here but I am not sure. I want something to give them to use to and be able to see the problem. Then call us to clean it. :mrgreen:
