Common problem:
- How long can the product be used and how long is its lifespan? The lifespan mainly depends on how you set the automatic switch time of the clock. It is recommended to set it to the off state when there is no one. Generally, it can be used for two to three years. The nominal lifespan of each tube reaches 10,000 hours! Of course, friends who play love generally don't worry too much about the lifespan. Replace which tube is broken. It's easy to disassemble and assemble.

Pay attention:
1. The product is a loose part and requires simple assembly and welding by the customer.
2. The product does not have a glow tube (that is, 4 light bulbs that display numbers).
3. The product does not have a battery, if you need to remember the time function, you need to buy a CR1220 battery by yourself.
