It is hands down far superior in terms of quality and ease of use than my first scanner (3M Tru Def). I was hesitant to enter the market again but wanted to mainly for implant reasons. After talking with Laura and watching her presentation with my staff, we were sold! The i700 was extremely reasonable in price while being similar to units costing twice as much. CAD-Ray made this possible. I found their on line training to be adequate in learning the necessary skills to start scanning, I continue to watch these videos as I sharpen my skills. Initially I was concerned about the on line training. But now I actually prefer this way of training as it is self paced and you always have the library of videos to watch when needed. Laura has been there to answer questions and help me whenever needed and I’m talking on nights and weekends too! I admit I was was extremely hesitant to get another scanner, especially with an online outfit; but I have no regrets and highly recommend CAD-Ray and Laura for anyone needing a scanner! They provide excellent services.read less - 4/23/2022

Everyone in the company has extensive experience in dentistry. They have used all digital platforms and offer customers first hand experience. 2. Honesty. Based on their experience they share all the good/bad of different systems. They work with you to find a solution that works best for you. Not sell you the piece of the equipment that gives them the biggest commission. 3. Support. Cad-ray offers the missing piece of the dentist/digital manufacturer puzzle. Many other distributors sell you a piece of equipment but don’t have true day-to-day experience with that equipment. Cad-ray’s team openly share their expertise to help customers optimize their workflows with great technology. 4. Passionate. The Cad-ray team is extremely passionate about their craft. They truly believe in what they have to offer. I took Armen Mirzayan’s course on intraoral scanning and it was truly mind blowing. Armen’s insights will help any dentist optimize their craft. I purchased the full sprintray 3d printing ecosystem the help of Frank. I plan to purchase more equipment from cad-ray. Also, Jesse is a genius in regards to all aspect of digital workflows.

I needed to replace my Omnicam because the computer hardware was old and not able to keep up with the software upgrades. The computer upgrade costs from Sirona were cost-prohibitive (another reason why the Medit is so good) and I wasn't about to make the same mistake twice and replace it with another system from Sirona. I was a bit unsure about making a big switch but after speaking with Nick Statly at Cad-Ray, he eliminated all of my reservations and I ordered it. I've used it for the past week and love it. Setting it up and getting it running was simple. I would not describe this as a do it yourself process, it's much easier. If you can make a cup of coffee you can set the scanner up and start making excellent scans. All one needs to do is watch the very well laid out and easy to follow videos and save a lot of money. The image quality and ease of use hands down beats the Omnicam. Also during the current pandemic, I really feel better about being able to cold sterlize the tips vs the omnicam's just "wiping down." I almost hope my desktop scanner craps out so I can get the Medit desktop. I'm glad I listened to you Nick!!!read less - 6/04/2020

This was very early on before Armen had a vast number of technique and online support articles in his blog! Little was publicly known at the time about this new scanner but I felt confident in my purchase for a few reasons: 1) Armen had validated the product and was standing behind it... I knew of Armen from DentalTown and had many years of public posts to evaluate his character; 2) Limited demos available at the time; 3) some clinical accuracy data out of Europe that required zooming in on a powerpoint presentation that was recorded second-hand via camera phone ha! SO needless to say, I put a lot of eggs in the "Armen is standing behind this product" basket. We have NOT been disappointed. From personalized service from both Frank and Armen, to our vast success and joy using the product and deciding in late 2018 to buy a second Medit i500, I have nothing but good things to say about the product and Cad-Ray. What a bunch of self-less individuals. Armen has offered to remote in and I even took him up on the offer once and he remoted in immediately to take a look at something.

Before I put my hands on it, I had some prejudices against all scanners. They were bulky, laggy in capturing the images, etc. When I finally had the chance to use an intraoral scanner and get introductory training with Laura from CAD-RAY a few weeks ago, I totally changed my view of this product. Very soon, I was able to scan crown, bridge, and even denture cases. Of course, I have had some knowledge about the digital scanner from CEs provided in the past, but being able to apply it in the daily practice in such a short time was beyond my expectations. I would highly recommend MEDIT i700 and training from CAD-RAY.

After 3 years of use a significant issue came up with the scanner and they went above and beyond to get it back up and running.
