I was very disappointed with the delivery of my KDA Miner KA3 from Unigrade. It was very slow compared to other online stores and there were some issues with the payment. However, when I contacted customer service they were very helpful and resolved my issues in no time. I'm still not happy with the slow delivery but at least this store has reliable customer service.
They have always been reliable, I can count on them to provide me with residential proxies without fail. A quality that is hard to come by in this industry. Their SEO work is also top-notch and they are the only team I know of that knows how to market products on YouTube. I would recommend using proxy-store for your projects!
Everything was fine, apart from the fact that I didn't pass the KYC process at first. I like the design, and how friendly they are, and think I will stay to see if I can double my profit with them.
