I’ve actually used them for a while and they are quite professional compared to some other sites I've seen in Nigeria. The verification is pretty standard and they don't usually give you a hard time if your documents are clear. You can find more details about their setup for Aviator Nigeria

The mobile version is actually optimized quite well, so I haven't noticed any lag during my sessions. I mostly use my smartphone while commuting in Nigeria and it works like a charm. Their customer support also seems to respond fairly quickly if you have an issue. Just make sure you use a strong password for your account. It’s a solid choice if you want a premium feel while you play.
