CB3000 vs. CB6000: Which One Should I Choose?

Hi everyone My Lori unit has been giving me trouble, and my piercing isn’t staying put anymore (check the thread), so I need a temporary device while I figure out what to buy for the long term. I’m considering both the CB3000 and the CB6000 and would appreciate your thoughts on which one is the better choice. The only difference I can spot seems to be in their shape. A few people noted that the three holes on the 6000 aren’t ideal. Does the 3000 have those same issues? Are these devices robust enough, or do they crack if you sit down by mistake or knock them around? As you can tell, I’m completely lost!:oops: Kind regards Ben
