Yeah I noticed that. I think there's a way you can take out the entire bottom too to get access at everything but I haven't played around with it since I never had to clean it.
Hey everyone, just wanted to add that I've had my Alternate for a little less than a month now and last night part of the mouthpiece spontaneously cracked and a large chunk fell off. There was no cracking before and I haven't dropped the device at all. Used it fairly regularly since I got it...
