Those companies have already eliminated themselves from consideration based on ridiculous cost, ridiculous ongoing fees, and greater concern for petty proprietary posturing than for ensuring full functionality of their products to their usership. Typical dental tech company stuff.
The real decision was between Medit vs continuing life in analog dentistry. Medit through Cad-ray was really the only choice. Awesome packages , awesome access to free training videos, awesome software updates, awesome access to live support, awesome support staff.
There's just nothing better in dentistry than to get a great product AND a chance to stick it to the man.read less - 6/16/2020

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. Passion. 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.

I considered some of my local equipment reps, as well as cad-ray. Cad-ray won out due to their efficiency, speed of service, and knowledge. Their online presence makes it easy to get help via messaging, social media, or phone.
The scanner itself works great, but make sure to contact them to get the minimum specs required for a laptop -- it will make a difference in how the scanner performs.
To make the scanner mobile, I purchased this cart from Staples: https://www.staples.com/Oklahoma-Sound-Premium-Audio-Visual-Presentation-Cart-40-1-2-H-x-18-W-x-30-D-Black-Ivory-Wood/product_932437.
Lastly, I purchased "3M Dual Lock Fastener" to keep the power module attached to the wand from falling off the cart. I carry the scanner between two offices, so I wanted something sturdy, but removable. (see in photos). The hockey puck shaped holder (comes with the scanner) works great for holding the wand itself.read less - 10/10/2019

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
