I use the venum challenger- these hold up very well and I really like the dual density rubber that they use. These also fit amazing when you follow the instructions.
Been using a venum one from amazon past 2 years. No complaints.
I've been using the Venum Challenger Mouthguard for a long time now and it's worked well for me. Nothing fancy just does what it's supposed to do

have you tried the rubber sports type? They're very chewy but bulky. https://www.amazon.ca/Venum-616-Challenger-Mouthguard/dp/B00F2U1CTQ/ref=sr_1_1?crid=1PZ8JHFTWHXYT&keywords=venum+mouthguard&qid=1549660187&sprefix=venum+mou%2Caps%2C153&sr=8-1

Yea you boil it but looks pretty easy..
Works well, you mold it to your mouth with boiling water so it fits great.
I have this mouthguard and love it: http://www.amazon.com/Venum-Challenger-Mouthguard-Red-Devi/dp/B00F2U1CTQ/ref=sr_1_1?ie=UTF8&qid=1429393116&sr=8-1&keywords=venum+mouthguard
Easy to hiss/breath.
Hmm... judging by the down-votes, you might be onto something. I better do some field research. Luckily, I have mouth guards on Subscribe and Save with Amazon:
