3-in-1 thermal styling brush

The SOIOBLQY SM-730 combines a 1.5 inch curling brush, straightening brush and styling comb in a single corded electric tool. It targets users who want smooth blowout styles, soft curls or added volume without switching between multiple devices. The 33 cm length and 500 g weight suit home styling and travel use alike.

Dual PTC heating with ionic care

Dual PTC heaters deliver rapid heat-up and stable temperature control shown on an LCD display in Fahrenheit or Celsius. The ionic system releases 300 million negative ions to reduce frizz, static and flyaways during use. A 360° swivel cord prevents tangling while the 60-minute auto shut-off adds safety.

Three temperature settings and auto-lock

Three preset temperatures match hair type: 320 °F for damaged or fine hair, 355 °F for normal or colour-treated hair, and 390 °F for thick or coarse hair. One-button adjustment includes a 5-second auto-lock function to prevent accidental changes. The tool carries UL859, CE and RoHS certification.

Questions about this item

How do I start styling with the 1.5 inch barrel and what step do users often miss?

Plug the 360° swivel cord into a mains socket, press the power button once, then use the same button to cycle to 320, 355 or 390 degrees — the step often missed is waiting for the LCD to show the selected temperature before brushing.

What part of the SM-730 will need replacement after extended use?

The dual PTC heating elements and ionic emitter are sealed inside the barrel; no user-serviceable parts are designed to be replaced, so the tool is used until the 60-minute auto shut-off or heating performance declines.

What is the first limitation I will hit during a long blowout session?

The 60-minute auto shut-off (UL859 certified) will cut power first; after it triggers you must let the brush cool and restart it to continue styling.
