I finally did it in the fall of 2019 and haven't looked back. I was hesitant mostly because I didn't want to spend a lot on $$$ on something that I don't end up implementing. I found that I love scanning, I feel like it has improved my quality of preps and my OCD of being able to verify accuracy. I recommend Cad-ray because they want you to succeed. They are always available. They have been through this process many times, they know what does and doesn't work. My experience is with the Medit i500 IOS.read less - 6/19/2020

I have used a few different scanners since i have been a dental assistant and have had several complications as far as: how long the scanner would take to load the image, The scanner not catching the image and even the system constantly kicking me out. With the i500 intra-oral scanner i have the BEST experience. I am happy and my patients are happier! I recommend the Medit i500 Intra-oral scanner to anyone who has never used it before! You wont be disappointed! 5 Stars for sure!!!!

A staff member broke the lens on the Trios and while waiting 3 weeks for an RMA to send it to Poland for six weeks to get it repaired, Carestream was sniffing around and suggested that I trade in my Trios so I did which began a 4 month nightmare with their piece of junk scanner. Absolutely awful customer service from both 3Shape and Carestream. I needed a scanner and had heard great things about it the Medit i500 at the Florida Academy of Coesmetic Dentistry so I got one. It works really well and Medit keeps adding new and useful features and their architecture is completely open. Two weeks ago, my i500 died so I contacted Cad-Ray surrport and I had a new unit in my office 24 hours later! That's absolutely unheard of in the industry!!! Both Cad-Ray and Medit have positioned themselves to be industry giant killers and they're doing it. The i500 is a phenomenal scanner at a phenomenal price point and service and guidance at Cad-Ray is just plain excellent.If you are thinking about getting a scanner, do it!

I purchased a medit i500 scanner from my lap, they wanted to use it for courses which aren't happening now so he didn't want to be sitting with this expensive piece of technology sitting around. Before purchasing he and I both talked to the Nobel sales rep who assured me that everything would transfer over just fine. I was concerned about the learning curve and wanted to be sure that I would have tech support. I asked the rep directly and he assured me again that everything would be great and he would come do an in-depth training with me. Long story short, the sales rep had no clue what he was doing and put very little effort in to helping me once the purchase was complete. I asked him over the phone how to do a few things and his response was to call CAD-Ray. They explained that this happens, they would love to help me but asked that I purchase the service package. That was a game changer. Now all of my questions getting answered, their response time is amazing and their understanding of the machine is by far better then the Nobel reps. The scanner is great but combine that with their tech support and I feel like I'm set up for success. If I were to do this again, I would skip the headache of trying to save a little bit of money and purchase it through CAD-Ray. But even with making the mistake, I feel like they have programs and support set up to point me in the right direction.read less - 10/15/2020

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

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 fact that one of the employees of Medit (an engineer?) posts on the cad-Ray Facebook group speaks volumes of the vendor-mfg relations.
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. I had some slow scans at first but upgraded from 8gb to 32gb ram and also got some coaching from customer service (Frank) to get me up to speed.
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) is heavy and sticks to the countertop without needing any adhesive.read less - 10/12/2019
