Great! But consider size
Good quality product, and nasty-looking ; ) as advertised, the ring is larger than the average, which might suit thicker dicks, but I’ve found few ppl so far can open their mouths wide enough! (I can). S(A)X make their own version - worth a comparison. FYI - a spider gag will keep the lips, roof & floor of the mouth away from the cock to keep things open; so the bulk of the pleasure comes from friction against the back of the throat: a bit different to a normal blowjob. But the pleasure also comes from the forced openness and the evil look of the contraption. This applies to all brands.
