If you need maximum durability and a premium feel: look for metal core + replaceable grip sleeves (e.g., GripMaster Pro).
If comfort and slip resistance are top priorities: choose full silicone grips (ComfortTurn).
If you carry many keys and want organization plus leverage: consider a folding multi-key handle (FoldAway).
For severe weakness or stiff locks: choose a lever-style or powered option (TurnRight or SmartGrip).
For budget or trial: start with a simple clip-on or silicone sleeve (EZTurn or ComfortTurn).
For arthritis or joint pain: choose devices advertised for medical/ergonomic support (ArthriAid).

Consider these factors:

Key compatibility: measure key head size and shape; some extenders accept only standard flat heads.
Portability: pocket space vs. purse vs. home use.
Hygiene: silicone and washable parts are easier to clean.
Attachment security: ensure the extender won’t slip off during use.
Aesthetics and visibility: bright colors help find keys quickly.

Wash silicone sleeves with mild soap and water; dry thoroughly.
Inspect plastic adapters for cracks periodically.
Keep folding mechanisms free of grit and occasionally apply a tiny drop of lubricant to metal hinges.
For powered extenders, follow manufacturer instructions for battery replacement and charging.
