As someone who has used Tiaoyeer to purchase a digital scale, I can say without a doubt that you should avoid using this online retailer. However, despite the fact that their website is simple to navigate and that their prices might appear to be fair, the quality of their products and their customer support are both severely lacking. After only a few weeks of using the digital scale that I bought from Tiaoyeer, I observed that it was inaccurate and inconsistent in its readings. I attempted to get assistance from their customer support team, but the representative who answered my call was unhelpful and condescending. They recommended that I re-calibrate the scale on my own, despite the fact that I did not have any prior experience in doing so. When I attempted to re-calibrate the scale, I found that the instructions that were supplied were not very clear and led to a lot of confusion. After several failed attempts, I attempted to get in touch with Tiaoyeer once more, but this time I was greeted with even more frustration than before. My interaction with the representative was impolite and unprofessional, and they seemed more interested in getting the conversation over with than in assisting me in finding a solution to the problem I was having. After some time, I became frustrated with the scale's inability to be fixed and made the decision to buy a replacement from a different vendor. When I got the new scale, I immediately observed a significant difference in the quality and accuracy compared to the scale that I had bought from Tiaoyeer. This was the case as soon as I got the new scale. In conclusion, I definitely recommend that you do not make use of Tiaoyeer. Because of their low standards for product quality and customer support, dealing with them is not worth the trouble.
