Well I'm looking at these items purely for the novelty factor, it's something new. The hole in the plug is for extended wear as these are dialators. I've never been able to wear anything for a longer period [never really even wanted to] because the pressure would just build up and it became uncomfortable. And I don't fart all the time, yet it's different without the plug in. There are even little plugs that come with these meo tunnels, to cap them. ;)
But the meo is expensive.
Not sure it is a good idea to try dilation with a material as hard as metal (or glass, or ceramics) alone (at least at medium levels or larger). These are hard on the tissues, and force even not too excessive may cause injury. Rather — well, at least from my experience — in order to play with a glass toy of a certain girth I had to be warmed up / dilated to a level higher than that of the hard toy.
I'm the same as you regarding long-term wear. I have only one toy that I use that way, seldom too, and only because it is in the goldilocks zone in every respect except fireworks. Not too big, not too small; not too hard, not too soft, and of the shape which is just right.
Regarding volatiles, I have never got to test myself, as I destroyed the tunnels asap, but I read a review from someone who actually tried to use a tunnel long-term. With an 'instrument' like this, you lose all control over gas containment/displacement. The results were entirely predictable, I should say, and I'm glad someone tested it for me ;)
If you just want to try this kind of toy as a novelty, then I would go for the meo, due to hardness. Who knows, perhaps the base width will be enough for you to keep it in and hold on to it, and at least you'll know that it won't bend and cause the entire doohickey to dive in.
As for the price, it's not that expensive...
It's nice to see that different companies are iterating on the original, pathetic design. One day, they may even make a fully usable/safe toy ;)
