The best part about United Fulfillment Solutions is that they are reliable with fast shipping times in addition to great customer service. I have never had an issue with any orders or issues with their products. There isn't anything I dislike about them. They are quick to respond to emails and make sure your needs are met. When there is a problem with their products, they send out new ones as soon as possible. Shipping can be slow depending on what time of year it is, but other than that, everything runs smoothly. They have helped me get my product delivered faster and more efficiently.
