Actually I found that rather surprising. When you fill the basket it's actually upside down when compared to the final postion in the bucket. The lid goes on the bottom side and is solid. The topside has a rather large hole in the middle where the exhaled gas enters the bucket from the head. If he missed that hole he would have likely missed anything written onto the the basket, too. It's a pretty simple procedure if you think along ... .
I agree it's a good thing that Steam Machines is going for certification. It'll offer a good alternative to APD's units, and should do well. If you ever get a chance give it a try. Great lil' rig, breathes so well.
