I got two guards, Dual Laminate Teeth Grinding Day Guard, and Flexible Super Hard Night Guard (Back Cut). I had used the Dual Laminate one primarily but then I had been grinding so hard I separated the layers. It was still useable, I just had to nest the layers together before putting it on. Then my guard went missing so I started using the back cut one and I like that one so much more. It feels more hardy. That one I have now reordered.
The process to make your own impressions wasn't easy (I had originally wanted bottom guards) but the team at Sporting Smiles was helpful and kind, even sent me extra putty when my first couple tries were flops. I ended up switching to a top guard because that was easier for me to do.
Overall, good customer service and more affordable than the dentist office. I would highly recommend.
