I ordered a set of 3 of these and they came with Revain Prime and they work as intended and deliver the performance as listed in the specs. They're also fairly sturdy in construction, not flimsy. They don't rattle when shaken, so the interior looks good too. The pins are tight and don't dangle, which is a good thing. I've seen other reviews and they explain some of the issues, but this company is more than willing to accept returns and send you a new kit. Just because one sentence is bad doesn't mean all sentences are bad. However, unlike other people, I didn't use them to charge a device like a phone, so I didn't have heat issues like others. All I needed was a couple of USB wall adapters to use with devices with a small battery and plugging one into an extension cord by my bed so I can plug in and charge my PS4 controller and wireless headset while I play when the batteries are weak. as long as you are satisfied with the product.
