Evidence boundary. Maker-reported facts are labeled below. We have not handled or tested these examples. This guide is not a product ranking or a verified physical lesson.
What do you need to establish first?
Movement path
Ask whether the exact model has a captive guide or separating mating surfaces. A photograph or slide-rail wording is not enough to establish captivity. Check guidance separately from what creates resistance.
Next: Request a model-specific underside or mechanism description.
Sound limit
Three-click names a layout; it is not a decibel rating. Plate contact, stops and your movement all need checking on the chosen configuration.
Next: Use the quiet guide if sound is a hard requirement.
Hand and pocket fit
Compare the full assembled dimensions with your available space. Thickness can change with plate choice; a body length alone is insufficient.
Next: Write down the exact plate/body configuration before comparing.
Named examples and what is known
LAUTIE Shuffle KK - 2099 Series
Guidance axis
Flat mating surfaces described by the maker; captive guide not established
For guidance, record a captive guide, separating mating surfaces or unknown. For resistance, record magnetic detents, a mechanical spring/track mechanism or unknown. These are separate axes: rail, magnetic and metal are not mutually exclusive product types. Material is a third specification. Choc illustrates why a product may contain magnets while describing its feedback through a spring bead. Model-specific push, return and regrip lessons still require real samples; this guide does not claim to teach those movements.
Three separate decisions
Movement decides what your fingers can do. Contact plates decide which parts touch. Body shape decides where you hold it. Compare each separately; a premium material name does not answer all three.
Check what can come apart
Before choosing a magnetic model, check retained magnets, removable parts and the maker’s handling instructions. Do not use an unknown separation mechanism as a trick tutorial. If loose parts are unacceptable in your setting, keep the candidate unresolved until its construction is documented.
When this example is not enough
This is a specification-reading example, not a ranking of sliders. We have not established which configuration feels smoother or lasts longer. Ask for model-specific documentation when the listing combines different bodies, plates or revisions.
