I actually use ip2location's demo page as well. I put together my own api that grabs ip to location data from the 4-5 sources that provide the information for free, and then look for similarities. So if a (city, region, country) is present 3/5 times, it defaults to that. If they're not any similarities, it will default to maxmind geoip2's demo (if it hasn't already used up the daily free lookups). And then cache it all of course. Works well for the limited amount of lookups I need.
