I have this gag in a cream/nude colour, though the previous one we had was black, and it's one of our favourite gags, for a few different reasons: The velcro fastening: while it doesn't allow for locking the gag on, we've found it to be secure and does allow for quick-release on the few occasions that it is safer for it to come off quickly. The press-studs: they hold the strap to the silicone piece and will detach (pop undone, when required); this allows the gag piece to be washed/boiled/whatever separately if you want, or for a different strap to be used instead. The material: this is good quality shiny silicone, which has stood up to quite a 'battering', has no discernible taste or smell, is washable... basically all the good things you expect from silicone, in particular that from Tantus silicone (though does collect dust/lint, for the same reason). The size: generally it's both a good insertable length (2.75") and girth (5" circumference, 1.75" x 1.5" max) to fill the mouth well without being unwearable due to being too long, or insufficiently short. The cock piece: it's a 'cock' with a defined head/glans and bit of shaft, but towards the base it narrows so the mouth (teeth/lips) can naturally close and relax a little and leave the cock inside, which leads to a bit less stress on the mouth/jaw than with other gags; obviously it's deeper than most ball gags, if you're just used to those. The panel piece; after the narrow section, it then widens into the flat panel shape (about 0.25" thick) to which the straps loop through two rectangular holes on each side; the presence of the panel greatly limits saliva leakage (though not accumulation inside, watch out for that) and due to the good seal it muffles sounds pretty well, but of course make sure the nose is unblocked due to the good mouth seal. Wearability: it's been tightly 'in place' for multiple hours at a time, perhaps with a bit of practice, but it does what you expect a gag to do for a long time, without the often unsafe or impractical discomfort of some other brands or types of gags. Basically, we think it's wonderful, and for what it is there's not much to improve. I can see that the strap may be too big for some, but it can be adapted or changed easily. With regard to hair catching in the Velcro, we're just careful or apply it over a hood with a mouth-hole! Every toy needs testing before integrating it into more complex play, so see how you are with this in different orientations (laying differently, standing, etc) and how safe it feels if it's secured tightly or pushed on (by a person or bed/object). This works for us and we highly recommend it, but everyone is shaped slightly differently and has different tolerances and comfort levels. I just wish Tantus would broaden the range a little and explore different shapes/girths/lengths, for greater variety and challenge. :)
