Yes, it’s reliable. I’m a pragmatic person. I don’t see them as a “replacement” for the real thing, but more as an alternative when you’re single, lonely, maybe not being treated particularly well (etc), or just want a great threesome, rave, or fun company! Why not all of the above situations? Some people may judge you for owning something like this, but at the end of the day, their opinion is worth a WTF. they’re not going to lick you and pay your bills.
