I decided to write my review, because I have read some negative comments, and I am convinced that they are fake comments, because I was satisfied with my purchase. I was looking for where to buy Goldshell KD5, and obviously I was looking for something at a competitive price, and I found justminer. The site is quite easy to use, and I used bitcoin for payment. They shipped 1 day after I paid, and I received the miners by express delivery within a few days (about 5 days). By the way, shipping is free, and I like that too. I can say that if you want to buy miners, you can do it on justminer and you won't regret it.
