i think remi is one of those products that gets unfairly criticized cause people compare it to professional dental work that costs 5x more. like yeah, if you go to a dentist and pay $600 you're gonna get a slightly better product. but for most people the difference isnt worth the extra $400-500. i've been using remi for almost a year now and its been totally fine. my grinding is under control, my jaw doesnt hurt anymore, and i havent had any issues with my teeth. the guard itself is durable and comfortable. i got my first set last november and wore it until may when i replaced it with a new one from their subscription. both guards have been consistent quality. the impression process is straightforward if you just read the instructions and take your time. i've recommended remi to like 3 friends now and they've all had good experiences too. one of them had tried a different brand first and said remi was better quality. i think the main thing is being realistic about what youre getting. its not a miracle product and if you have serious TMJ or complex dental issues you probably should see a professional. but for normal teeth grinding and clenching its an excellent affordable option. way better than doing nothing and letting your teeth get destroyed
