Anytime you see words for a service like Diamond, Platinum, Gold, copper or steal, run away.
A good service does not need stones or metals to advertise.
I've dealt with this reseller before and didn't have a great experience. Around the time Express had their 2 week outage in the Spring, the guy running it decided to pull all of my reseller credits with the promise that he was putting a new reseller panel together. The new reseller panel did come to be but without the credits I was owed. Took a month of back and forth, a lot of text messages and phone calls but I was eventually given back what I was owed and we parted ways. I went back to using the regular Express panel and I don't know what became of the new panel he put together
Do a Google search on the provider and I think you will get your answer. These people do a lot of scamming, they claim to offer 4k.
