very HARD to use
So I saw the hilarious video review on youtube and immediately went to amazon to order myself one.  This one .... is even harder to 'work' than the one on the video, which looked plenty hard enough.  Also, it gave me two mouth sores after using it (yes, yes, I washed it thoroughly. it's just that it bruises the 'hinge' of your lip when you try to flex it).  So, boo.<br /><br />The part that goes in your mouth is painfully large, and the lips part is solid 'silicone' and very difficult to flex at all.  I don't really care about the 'exercising' aspect of it - I just wanted some laughs with my family.
