Going to leave my review from an advertiser standpoint as well.

The Good:

Fast, immediately delivery of tweets.
Fast payment confirmation.
Easy to use site.
The site loads fast.

The Bad:
It is per follower and not per tweet like most services. This needs a better explanation somewhere or to change to be in line with similar services.
The cost is super high compared to other similar services. I can get 100 tweets from higher quality followers on similar services for 5 dollars.
My tweet went out from three low quality accounts.
It isn't clear you are paying by followers and not tweets. This isn't how most services operate.

I wouldn't purchase again until some of these issues are resolved but cool service and always glad to help out others in the crypto space!
