Warranty on the life of disposable sealed co2 laser tubes
Warranty on Chinese made tubes is passed on to you by the 'importer' of the tube.
You must check his Terms and Conditions before you buy.

Is there any power warranty? Is it for 1 months or 3 months?

Since warranty is usually provided by the manufacturer, the unit has to go back to CHINA to the manufacturer. You are responsible for Round trip transportation costs TO and FROM the manufacturer in China.

Therefore upon failure, it is cheaper to discard the tube and purchase another one.

It is often cheaper to buy 5 Chinese made tubes than it is to buy one Made in the USA.
However, the one made in the USA tube works longer than 10 disposable tubes.

Famous Chinese proverb says: "you get what you pay for".
