Sub par manufacture - Barska Top Mounted Fixed Iron Sight

I was very excited to get this item seemed like a very utilitarian and useful site. Novel concept of laser in front sight I receive this site and inserted the batteries, at which time the local switch worked only intermittently would come on flash and blank several times then would most of the time stay on. The pressure switch which acompanied the item was completely non-functional. Very difficult to use a site like this or the laser for it without having the pressure switch to allow remote activation. I reluctantly returned the item and never even mounted it to a firearm. As stated I would actually really like to have kept the site if it had even been moderately effective.
