It is based on DriverAgent (not Driver Booster), but has a different UI. It doesn't work very well, as it needs a bigger database of drivers. Unless you are missing drivers for some devices, or are experiencing issues with some devices. there's often not much need to update them. In some cases you can get performance increases by updating drivers. While this is a good thing, often not will you not notice any difference in performance and sometimes driver update software will install incompatible drivers which can cause issues, until the previous working driver is reinstalled.
The review at Windows Club is is misleading. While it states that "Outdated device drivers are one of the primary causes why your Windows PC could get Blue Screens," this is simply not true. You are actually much more likely to get blue screens, after updating drivers. For example, if a new driver is buggy, or not actually compatible with the device it was installed for. Outdated drivers, won't suddenly start causing blue screens due to being outdated. If a driver causes blue screens, it most likely be problematic from the moment it is installed.
If you do want to use a driver updater, I recommend DriverHub. It is free, has a very large database of drivers and works very well. It comes bundled with extra software, but due to recent changes to its installer, nothing extra gets installed unless you want it to. You have to manually choose if you want to install any extras or not, which is a welcome change. I prefer it to Driver Booster, because it has a larger database of drivers.
As I mentioned above, it's not a rebrand of Driver Booster. It is not the only driver update software which has copied the UI of Driver Booster. With regards to it being a PUP, just about any type of driver update or cleaning software is often classified as PUPs these days. So the fact that it's classified as a PUP doesn't meant that it's harmful in any way.
