Good value for a night guard

I got the hybrid night guard after looking at a few places. The first order discount helped a lot. The impression kit came pretty fast. It took about 2 weeks total to get the guard back after I mailed the impressions. Fits really well and seems sturdy. Felt like a good purchase overall.

Easy to order, great fit

My old night guard broke so I needed a new one. Decided to try Corefit. Ordering the custom fit mouthguard was super easy. The impression kit came in like 4 days, then I sent it back. My new guard fit perfectly, no issues at all. Definitely better than the boil and bite ones I used to get.

Hey has anyone used a discount code on Corefit recently? Trying to figure out if I can stack the first-time buyer one with a holiday sale or something.

Nah, pretty sure you can't stack them. Every time I've tried, only one applies. Usually best to just use the highest percentage off you can find.

Yeah, I tried combining two last month and it didn't work. The site usually just picks the best one or tells you they can't be combined. Still worth checking for a good single code though!
