Looks very much like a TRUGLO, erm, spinoff - like exact. Could be that both companies buy from the same source and put a brand on it. I use a reflex sight on my 930 with good results BUT a shotgun is hard on sights. The first TRUGLO I mounted lost the glass in the first shooting session. It's advertised (as is this one) for HD use including shotguns. Truglo replaced the unit and turn time was reasonable. For warranty work you will have to deal with the company not the seller or Amazon. For that price it may be worth a try but will it be worth repairing or replacing? - I'd check on the company's policies and procedures for that. I'm not familiar the brand. Similar name brand units can be purchased at Walmart or the big box sporting goods stores.
