暗牢銀口 ("Silver Prisoner") is an indie adult SLG developed by TnDoys. Its defining features are its availability on portable platforms, its relatively small file size, and its specific niche appeal.

Despite being a stand/holder (which usually has no moving parts), some users reported the device being "very load" (likely a typo for "loud") or difficult to use. Furthermore, there are reports of the device turning off when there is no load, requiring users to "access the phone app to change the default settings". This implies that the V10 might incorporate some sort of power management smart chip that can be overly sensitive.
