There will be hiccups with any complex piece of machinery, but every time I have needed Cad-Ray, they have been there. I recently had a scanner go down. I called Cad-Ray tech support and they got me on the phone with Medit immediately. Within a day, a replacement scanner was sitting on my desk. It doesn't get much better than that.read less - 10/03/2024

We have omnicam and I hated it, multiple crushes, expensive monthly service fee, horrible support, etc. I was so frustrated and had to look for an alternative. Many mentioned itero to me and I was about to purchase it and suck another monthly fee until I came by Armen’s video about medit on one of the Facebook group in 2018. I was surprised with the image and the speed and started digging more and contacted Frank to explain the scanner more. Ended purchasing it late 2018 and I’m a happy user Since after. The support is excellent, Frank is there when you need any help plus the Facebook community is there to answer anything. Recently, I attended Armen’s course to learn how to mill from the medit and I got shocked by the AI and the options that the software has. This machine is a beast and you won’t regret it getting it from Armen and Frank. They go beyond and not like other salesman or equipments where you are left behind after they sale you and finish their training. We are in 2020 and I still get the same support as I bought it in 2018.read less - 1/09/2020

About two weeks after the order was placed, they called me up and said, “VHF just got an exclusive with “The Big Boys” so they are cutting ties with all the little independent distributors. They just called us, and we just found out. What this means is that we won’t be able to provide you service after purchasing the VHF mill that you just bought.”Now, they could have just left it at that. They could have said, “Sorry, it’s out of our hands.” They could have said, “We appreciate your business, but it’s not our fault.” They could have said, “That’s the way the cookie crumbles.”But they didn’t.Frank Weinstein calls me up and tells me that they want to make this right, so they are going to hook me up with a brand new Imes Coritec One+ for the same price as the VHF. The Coritec One+ is like the Mercedes of mills for in-office. This is the new model that just barely came out. It is a 5 axis mill. It does wet and dry milling. It does blocks and pucks. It mills all materials know to man, including Vibranium. It can also fly the space shuttle, and make all your wishes and dreams come true. It’s that good. It came with the laptop, Exocad, all the tools, and all the bells and whistles. It came fully loaded. It came white glove delivered to my office. It came with in office training. It came with the extra bur package. It came with everything and the kitchen sink.So, I paid 36k for a mill, and because of something that was not Cad-Rays fault, they ended up giving me a 60k mill for the same price.In the words of the great Tony Stark: “That’s how Dad did it.

I needed immediate assistance, because I was in the middle of a case. The person at CAD-RAY who had the knowledge to help me had just gotten into a car accident and was at the ER. Now most companies and people would have said “Sorry, we can’t help right now due to extenuating circumstances.” Not CAD-RAY! That person called me from the ER, in the middle of his personal problems, and gave me the needed information to solve my problem.

I've used CEREC as an instructor at a dental school and bought a used Planscan, Planmill for my private office. Both were hard to learn and the fees and cost associated with training were a bitter pill to swallow after the costs to purchase. The ease of seating restoration was instant. The scanning learning curve is quick. I have easily added occlusal guard scanning, and implant scanning and will be trying a digital denture soon.
The purchase was easy, the product came quickly and the set-up videos guided me through very necessary adjustments to my Laptop I never knew I needed. Learning the new features with each FREE update is a treat. The DIY option was an extra bonus as the $2000 rebate came without having to ask for it. Cad-ray has delivered more than I expected with the purchase of the fantastic Mediti500 scanner.
I've included my cart set up. purchased from Amazon for $68. Its stable, has room for the necessities. I've taken it home and back to the office half a dozen times and it transports the scanner safely. It also keeps the cords from being run over.
