When I went to Jiangjin for a marathon in April, I found that several keys of the Bluetooth keyboard I usually used could not be used. The fault key is located on the far right. If you look closely, there is a slight crack on the far right, which causes the keyboard side to tilt slightly, and there is no response when pressing the far right key. But once I'm afraid to hold down the cocked key, I can type again. I can't keep pressing with my third hand and then typing with my other two hands, can I?

After returning to Chongqing, I tried to stick the tilted keyboard with transparent glue, but it still didn't help. There is only one way to work temporarily, with two small clips, one on each side, so that you can type smoothly again. But this loses the portability of this keyboard. I bought this keyboard mainly to take it out for typing on different occasions. If I have to bring two long tail clips at the same time, I'd rather not take this keyboard!

I still can't leave this keyboard without thinking about it. So I tried to find a substitute. Originally, I bought this keyboard on the platform of "Get" mall, and it showed that it was out of stock long after it was sold out. Later, I found an upgraded product on JD.COM, at a price of 399 yuan, which was a little more favorable and had stronger functions than the original one. I took it at that time, and the goods arrived in JD.COM soon. I received it on the third day. The keyboard is bigger than I expected, but after increasing the key spacing, typing is not easy to make mistakes. Although it is a little expensive, it is a successful improvement. Great!

After that, I found the link of after-sales service in the order record of Get mall with curiosity, clicked in and submitted the claim. The next day, someone called me and said that the crack of the keyboard was the cause of long-term aging. In order to take care of old customers, I can exchange 100 yuan for a new one. I thought about it for a moment, and after being confirmed by the customer service (the customer service and the factory staff of Get also confirmed it for a long time), I completed the payment on the same day and sent the keyboard by SF Express. Two days later, I received a new keyboard, the same as the original one, engraved with the signature of "Liu Run *5 Minutes Business School".

In this way, I have two Bluetooth keyboards at once, both of which are very easy to use.

To sum up:

1. This is a successful experience of defending rights.

2. The brand "Liu Run" is not bad. I'm considering whether to buy his class.

The environment of online shopping is much better than a few years ago.
