The team at ElFo are always available to answer any questions we have, even if it's something as simple as "can I use your product?" This has been great for our business because they've helped us figure out what works best in terms of advertising methods that get results - so far everything looks good but this hasn't really changed anything yet since all decisions were made beforehand by other people (not just me). They're also very easy going which makes working together easier than you'd think. It took some time getting used to their payment system which was quite confusing compared to others who offer payouts via Paypal or Alipay etc., but once figured things worked well enough it wasn't too much hassle anymore. We haven't found many downsides about using them either. If there isn't already one listed here feel free ask away :) Their support staff can be reached through live chat 24/7 during normal office hours + weekends / holidays depending where you�.
