Which brand of domestic hydrogen absorber is better?

Hello, at present, there are relatively large hydrogen absorbers in China, such as the hydrogen degree household version produced by Dongguan Hydrogen Pulse Technology, the nano bubble hydrogen absorber produced by Shanghai Nano Barber, the hydrogen spring hydrogen absorber and the Colijn hydrogen absorber. But personally, Aubad is the kind with good cost performance, and the machine is more suitable for home use and small in size.
