After a year-long hiatus, I'll be resuming BJJ in a couple weeks now that my gf has received her 2nd vaccine. This time I want to stop tempting fate and get a mouthguard for protection against accidental elbows/knees to the face. Also want to do some ECQC stuff with the likes of Cecil and Southnarc and the like. Will I be well served with a basic boil and bite or do I need a more professional one?
This one is a customized one on Amazon, but I notice no dental warranty

Any insight/recommendations are appreciated!
