I've worn retainers for more than 20 years, and was ready for replacements. My original provider was no longer around, so I went to a competitor. I tried to get retainers, but after they told me none of my 3 impressions was satisfactory, I gave up and kept using my old retainer.
Then I found ClearRetain.
I took a chance on them. I'm glad I did. The cost was lower, and their mold was easier to use. The turnaround was extremely fast as well.
I have found my new retainer source, from now on.
