Is the quality of double mini fans reliable?

Did you buy it online? If there is, it depends on luck. Every online shopping has good reviews and bad reviews. You are very lucky. If what you get is genuine, it won't break after being used all the time. Unfortunately, the defective products are taken out from the defective products and received directly, or they are broken after being used once or twice. If you bought it in a store, ask the boss if you can exchange it or repair it for free. How long is the warranty period?

There are many brands of mini fans now, and the quality of a brand depends on the advertising investment of artificial products made of materials. The quality of brand fans with low prices and relatively reasonable prices purchased from many people will be more reliable.
