Some of you may be aware that drauka has been selling seedboxes for some time now, and has a great wealth of knowledge on the subject. What you may not know is he has been secretly creating an awesome seedbox site called DedisReturn! Also the site has super awesome graphics and a star wars themed named by a super awesome anonymous party who will not be named (*cough* ME *cough*).
He offers a wide selection of boxes (pretty much anything you can buy from OVH, and is currently running a promo for discounts on new users with him. The support is unparalleled from other boxes (although me pestering him constantly to do things may drive him insane eventually), and the prices are very competitive even without the possibility of a discount.
All in all the box itself works great, i'm currently on the Rebel Series - A Wing (pictured below) with a 2 TB hard drive extension and i'm loving it so far. I recently switched from Feralhosting because tbh I never really maxed out the speed and it just wasn't worth the money to me.
When you add it all up, the great price, service, and piece of mind knowing that your box comes from a trustworthy person like drauka (and also the awesome graphics/star wars theme from yours truly ) you really won't find a better site in my opinion.
