A lit mirror photograph can show the lighting arrangement and visible appearance. It cannot establish the electrical suitability of the complete product for a bathroom in a particular country. Keep those two review questions separate: what the buyer can observe in the image, and what must be supported by the actual offered components and applicable documentation.

Look at where the illuminated area sits relative to the mirror edge and the surrounding cabinet design. Ask for an overall view and a closer view of any uneven appearance. Camera exposure and the room's ambient light can affect the image, so do not treat a photograph as a calibrated measurement of brightness or color.
Request identification of the power supply, light source and relevant control components offered for the order. The information should correspond to the actual specification, rather than a similar product shown elsewhere. If the supplier proposes an alternative component, ask which requirement changes and what supporting information accompanies it.
Electrical installation and bathroom use depend on the destination's requirements and the actual installation location. Ask the responsible local professional what documents and installation conditions are needed. A working demonstration does not replace that assessment, and a component marking should not be assumed to cover the entire assembled product.
Clarify how a power supply or other serviceable part can be reached after installation. Discuss the route for wiring and the connection arrangement with the installer. A neat front view may conceal a service access problem that only becomes obvious when the mirror is mounted against the wall.
Keep the visual review notes alongside the specification and outstanding compliance questions. An appearance approval should state what was reviewed. This allows design decisions to progress while preventing an attractive photograph from becoming an unsupported statement that every electrical requirement has been satisfied.
For a bathroom mirror or vanity enquiry, send VSME the intended lighting effect, installation location and available supply information. Ask the quotation to identify the offered components, supporting documents and site connection responsibilities.
