Dentist.net is great when you get what you ordered. But if you don't, customer service is none existent. Email is the only way to communicate with them, which goes unanswered. If he doesn't have what you ordered, he'll ship you something else. Try to return it is an impossibility since you need an RMA number to return it and the only way to request a RMA number is by sending him an email, which goes unanswered. Sorry, I didn't look up these reviews before I ordered from him.
