I've been with ServInt for almost five years now and am very happy that I made the decision to go with them. I was looking for a solid VPS provider and had whittled the options down to three companies. Pre-sales support was excellent and the technical support I've received since signing up has been second-to-none.
I believe this is the second or third round of free upgrades since I joined. It represents excellent value for money and I wouldn't hesitate recommending ServInt's products to anyone looking for a web hosting provider.
