Which company does the visitor registration management system well?

I checked, Desheng is the best, Qian Lin is also good, and Hengtai Zhuocheng (Tianyu) is the worst. It is said that the repair rate of Hengtai Tianyu is extremely high, and all of them are repaired with pirated software and hard disks. Many customers have been cheated. Their boss cheated a group of customers with Hengtai Tianyu Company, and finally there was no way out. In order to cheat, Hengtai Zhuocheng registered again. I wonder if it's true. There is no smoke without fire, which should be true. Everyone should make a good choice!
