Opro instant custom-fit mouthguard: anyone used it? Standard vs Enhanced

[wolffanghameha]

I'm buying one of these, but I'm unsure which level to get. Enhanced (or Ultimate, a thinner version of Enhanced) is the one they say for sports like boxing or mma where the head is an intentional target. But they say Enhanced has a hard outer layer. I'm unsure if that'll hurt more when getting punched, since my current cheap mouthguard has hard plastic on the outside, which after moulding had a sharp bit that easily hurts my lip, even with a light punch.

Anyone used this mouthguard, especially the Enhanced or Ultimate protection levels?

edit: well I ordered the Ultimate one. Bout £45-£50. I'll post how it is once I have it, mould it and have been hit with it on.

I have the enhanced. So far, I only put it in for five minutes of warmups, then switched back to my old Sisu. This thing is too thick for my current taste. I might put it in during coniditioning sessions and see if I get used to it, if not I'm done with it.
