AdGate - full name AdGate Media - is a great offerwall that is trustworthy. They can be easily found on most sites that have offerwalls, from various apps to websites. Usually they have a lot of offers, some of them are high-paying as well. Their support is very nice, quick to respond, and if they promise to do something, they actually do. Compared to some awful offerwalls (yeah, you, OfferToro), they actually contact advertiser and you will get paid. So do not worry if your click did not get count for some reason, just contact them and you will soon get paid, unless you did something really wrong. Some users say that they did not get paid, but my experience was very positive with them and I would say they are pretty good.
