A: Satin edge means the mirror perimeter is frosted/sandblasted to create a semi-translucent, matte finish. When backlit LEDs turn on, light shines evenly through this satin edge — you see a continuous, soft glow, not individual bright dots (LED hotspots). Regular backlit mirrors often have untreated edges that reveal the LED dots or create glare. The satin edge is also fingerprint-resistant and stain-resistant, easier to clean, and delivers a true hotel-grade look.

A: No. The satin edge is created by chemical etching or physical sandblasting of the glass itself — not a film, not a coating. Therefore:

• No peeling or bubbling

• No mold (glass does not support mold growth)

• No yellowing (no organic materials to age)

The entire mirror is rated IP44 splash-proof. Installed in bathroom zone 2 (not directly under the shower), expect 5–8+ years of like-new appearance.

A: This mirror uses stepless dimming (0–100%) . Via the smart touch switch:

• Single tap: On/Off

• Long press: Brightness smoothly increases or decreases — release at your desired level

Many models also include last-brightness memory — the mirror recalls your preferred brightness when turned on again. Unlike stepped dimming (fixed levels), stepless dimming lets you find the exact brightness for any situation.

A: Waterproofing is unaffected — the mirror has uniform edge sealing that works identically in horizontal or vertical orientation.

Regarding the touch switch — check before purchase:

• Some models have a switch fixed to one side (e.g., bottom right). Reversing may move it to the top left — functional but may feel awkward.

• Premium models use a center-mounted switch or dual-position switch that remains accessible in both orientations.

• Some reversible mirrors (including BOLEN models) place the switch on the bottom edge, which stays at the bottom regardless of orientation.

A: Yes, a pre-wired power source (hardwire or outlet depending on the model) is required. Installation steps:

1. Decide orientation (horizontal or vertical)

2. Mark and drill holes using the back mounting slots

3. Install wall anchors

4. Connect power wiring (electrician recommended)

5. Hang the mirror and secure

Benefit of reversible design: You can decide the orientation on-site — no need to commit beforehand. We include dual-orientation positioning stickers to minimize drilling errors
