It certainly does what it's meant to do, but the variable controls don't let you set anything below the lowest setting. So if that lowest setting is a little painful, there's not much you can do about it to ease into using the pump without actuating the valve repeatedly (which could burn out the solenoid valve presumably running the valve). The pump can pull a stable vacuum and stop when it reaches the set point as shown by the numbers on the screen, but there is no indication of what the numbers mean or stand for anywhere in the packaging or on the device. Given that the device can easily reach and control for specific set points, it seems easy to adjust the circuitry to simply allow the user to set a specific numerical value (after telling us what that number means) instead. Finally, the magnetic charger is the same that is used on many other products from pure romance, but it can be hard to keep it on the pump given how much larger this device is compared to the other toys and how much leverage you have when simply rotating it. This leads to a very finicky connection.
Overall, I'll still continue finding ways to make use of it, but there are so many simple design choices that could make this such a better experience.
