Why asking which is best needs a spec-by-spec read
RENPHO US lists the Eyeris 3 Eye Massager and the Eyeris Caligo Eye Massager in its eye massager collection. RENPHO US
This guide sorts the stated facts by device so you can see which facts belong to which model. Beminda Steam Therapy Pro is a rechargeable, hands-free steam eye mask. It joins the comparison as a third device. The RENPHO figures are RENPHO's statements about its own models, and the Beminda figures are Beminda's statements about its own product, so none is moved from one device to another. This guide does not rank the three devices or name a best one. If you came looking for a single winner, the more useful result is a clear view of what each maker says, laid out so you can compare listings on the same terms.
What RENPHO's collection page lists
On its US eye massager collection page, RENPHO notes voice control for the Eyeris 3 and describes the Eyeris Caligo as a mist-based model. RENPHO US
Those two notes work as headlines for the two names. The sections below draw on each model's own product page for the longer feature lists, and each fact stays attached to the device it was stated for.
Eyeris Caligo: the detachable mist module and its two modes
According to RENPHO US, the Eyeris Caligo features a detachable mist module with two mist modes, continuous and interval. RENPHO US
Beminda's current model names its modes continuous warm mist, interval warm mist and cool mist. This is noted for comparison of wording only.

In format terms, RENPHO lists the Eyeris 3 with a removable, freezable gel mask. Renpho RENPHO lists the Eyeris Caligo with a detachable mist module. RENPHO US
The heating range is a RENPHO figure for the Eyeris 3. This guide attaches it to the Eyeris 3 and does not apply it to the Caligo or to Beminda.
Session structure: selectable timers vs. three 12-minute modes
RENPHO US lists a 5/10/15-minute auto-off timer for the Eyeris Caligo. RENPHO US Beminda's current model has three 12-minute modes. A warm mode runs 12 minutes, including approximately four minutes of warm-up. The warm-up is part of that 12-minute total rather than an extra phase.
The two makers word their session figures differently. RENPHO US words its figure as an auto-off timer. Beminda words its figure as the length of each mode. The three Beminda modes share one length and differ in mist type: continuous warm, interval warm and cool.
This guide does not say which structure suits which person. See also why a warm-up time figure is worth reading closely.
The Beminda reservoir: bottled drinking water for the current S-400R only
Beminda's current guide for the verified current S-400R / Steam Therapy Pro specifies using still, unflavored bottled drinking water only. Do not add anything else. Empty, clean and dry the mask after each use, following the current S-400R setup and care manual.
The instruction applies to the verified current model, not legacy or unknown devices. Before applying it, confirm that your unit is the verified current S-400R / Steam Therapy Pro. The water instruction is a Beminda instruction and is not a statement about what any RENPHO module uses. Because the instruction names one model, it should not be applied to another device.
How to use these specs, and what they cannot tell you
Use these questions on any listing, including the three devices covered here.
- Which exact model name does each figure belong to?
- Is a number a timer setting or the length of a mode?
- Is fit stated as a travel distance, a set of levels or a range?
- Which format does the maker name: a mist module, a freezable gel insert or a steam mask?
- If a fill instruction is given, which exact model does it name?
- Does the page say what the device is not for?
This guide reports hardware and session specifications only, and it makes no comfort, health or outcome claim about any of the three devices.
The figures here come from the RENPHO pages cited above and from Beminda's own product information. For anything not stated above, such as the liquid used by the Caligo's mist module or whether its mist is warm or cool, check RENPHO's own listing and manual. More generally, check each manufacturer's full product listing and manual for additional specifications before comparing devices.
