The only thing I disliked about their services was that it had nothing really bad but they were also very friendly, helpful and professional! They will always help you out if there's anything wrong with your account or website which makes them my favorite advertiser for sure! Give their service a try if you want great customer support in case of any issues. Their rates are not too high either as long as you have enough traffic. If you're looking for quality adverts then look no further than cpmstar! Great ads at good prices! We use them mainly because our site gets loads of visits from Europe so we needed decent foreign targeting options available. The service has been great so far, and it was easy for us to get started with them. I can't think of anything that I dislike about them yet. They have helped our business grow by generating more revenue for our site. I would recommend them to any website looking to increase their revenue. We are able to generate additional revenue from ads displayed on our website. It's great because we don't have to pay anyone else to do this work.
