TRYFUN Black Hole Mini: The Pocket-Sized Stamina Trainer
Looking to build your endurance or just enjoy a quick, intense release?
The TRYFUN Black Hole Mini is designed to help you last longer while feeling great. It is marketed as a "training" device because the textures and vibrations are tuned to help you practice controlling your climax.
A common concern with "mini" toys is that they might be too tight. This device solves that with a smart semi-open design (a flexible groove running down the side).
This allows the sleeve to expand and breathe, ensuring it fits comfortably regardless of your girth, without feeling constricting.
With one simple button, you can cycle through 10 vibration patterns, moving from a gentle buzz to a high-speed pulse to test your limits.
-
Build Your Stamina: Designed to simulate "training," the firm vibrations help you practice edging and sensation control to improve your performance in the bedroom.
-
Fits Everyone: The unique "expansion groove" on the side lets the sleeve stretch to accommodate any size, preventing that uncomfortable suction feeling found in other small toys.
-
Ultra-Discreet: It is small enough to hide anywhere, whisper-quiet (under 55dB), and completely waterproof for easy cleanup.
Why it works: The silicone is engineered to be "semi-soft"—firm enough to give intense feedback, but soft enough to feel realistic.

How it Compares:
-
More comfortable than closed sleeves: Because it is semi-open, it doesn't create a vacuum or "too tight" suction, making it much easier to use for longer sessions than a standard closed tube.
-
Better than manual toys: Unlike basic eggs or sleeves, this has a rechargeable motor built-in, so you get powerful vibration without needing bulky batteries.
-
Easier to clean: The open design means you can rinse the inside thoroughly and dry it quickly, preventing the hygiene issues common with deep, closed sleeves.
