The product I was sent was a no-name knock off, but it was the same product, just relabled so all was good.  No worries, that company no longer has their knock offs on this listing.  This works well from the few times I've used it, and does NOT mix water into the container to spray, it uses a venturi style suction to pull the fluid out, so when you are finished you can return the rest of the product into the original container without contaminating it or diluting it.  I don't recall the name of the merchant that sold me the knock off, but I have to give them five stars as well because as soon as I pointed out the issue they refunded my money 100% and told me to keep the sprayer and removed their listing so I cannot knock them but so much.
