✱Magnetic fluid quality warranty details.

Magnetic fluid has a lifetime. It's like a laptop battery.

When the magnetic fluid is not moving, its life is almost negligible. As such, the lifespan may vary depending on how it is used.

Since the products developed by Burnslab did not exist before, we are conducting self-testing with a test device manufactured by ourselves to measure the guaranteed lifetime.

We can guarantee you about 2,000 to 3,000 hours of operation time. 

Even if the guaranteed life time has been exceeded, this does not mean that it cannot be used.

After the guaranteed life time, the deterioration of magnetic fluid starts to show little by little (viscosity increases slightly).

But once it starts to work, it's barely visible to the eye.

Severely deteriorated magnetic fluid and contaminated glass bottle can be easily replaced by the user.

You can purchase a 'Magnetic fluid cell' separately from BurnSlap's official web page and replace it yourself.

BurnSlap receives only 'Magnetic fluid cell' when requesting repairs for magnetic fluid related defects.

If you send the entire product back, additional shipping and additional repair charges will apply.

It is normal for fine powder to adhere to the surface of magnetic fluid.

It is a necessary element to maintain the quality of magnetic fluid.

This powder is barely visible once it starts working.

What appears to be tiny dust particles can float in the clear carrier liquid.

If large visible dust (more than 2mm in diameter) floats, it is a manufacturing defect and we can provide repair and replacement service.

Like LCD monitors, there may be bad spots on the glass bottle.

Magnetic fluid may stick to those bad spots.

If you find two or more bad spots with a diameter of more than 2mm on the product you purchased, we will accept it as a defect and offer repair or replacement service from us.

Atypical patterns or air bubbles may be seen on the glass bottle due to refraction of the internal LED light.

However, this is not a defect, it is a natural phenomenon of the way the glass bottle is manufactured.

However, if serious air bubbles are found in the glass bottle to the extent that it adversely affects durability, we discard them in advance.
