I'm not sure it comes down to connection. I am in Australia with pretty poor speeds in general. I had two Chrome pages running with the extension, one with the key word 'traditional' and the other with 'boat' (There is probably a way to have both key words on the one page but I don't know how to). I got a house boat the other night that I am assuming was tossed back in and I just happened to be looking at the page as it was refreshed and saw it come up and jumped on it quickly. I had secured it pretty much before the extension even told me the keywords had come up. So maybe it's notifying not as quickly as actually seeing it if that makes sense? That was just my experience anyway that by the time it notified me, they were gone already. I just happened to get really lucky.
