To claim your replacement, please bring back your tubes to our test center located in the Philippines and we will exchange it with a new one. If the product is already discontinued, we will replace it with other tubes of equivalent value.
If you cannot visit our test center, you may exchange it by mail. Please pack the tubes very well because any delivery damage will void the warranty. And shipping cost from the Philippines to US/Europe is around $40.
Tubes on clearance sale are usually not covered by warranty. We will provide as much information as possible for you to know the true condition of the tubes. Information we can provide includes test data, high resolution photo, video call, or any other information.
