The "China" word already make me feel unsafe.

Aerosol doesn't last long in storage and have an expired date. Which is very short. And it is not cheap.

This kind of aerosol don't have the gauge to tell me what are the pressure inside.

So the "Light weight, efficient and last long." is questionable.

I will buy the cheap wan put it in my car.

It just a adv demo. Doesn't tell me anything.

The bad fact is overwhelm the good.

Actually I brought aerosol type before. Back 17yrs ago. Before you know it exist.

The shelf life is only 2yrs. By the yrs 6 (I m lazy to replace it), I try to squeeze, there is no more pressure inside.

The reuseable can tell me the pressure is still good or not. By checking the gauge.

If pressure low, I can bring it to refill that doesn't cost me much.

So the refilling method still cost me less in a long run.

For the aerosol type, I don't no is it good or not in the shelf. By the time I need it, it probably in low pressure. It don't have the gauge to tell me.

The only reason I want to get the aerosol type is to put inside my car. Cause the refill type is too big store under the car seat.

But not for my home.

You don't have proof. 

You don't have fact.

You don't have experience.

And it is a joke to just check the gauge and you called hassle.
