Recommendation sought

Hey community I would need a recommendation in terms of brake ventilation device for the private user. There are two variants I have had to say. Compressed air and manual. Those here in the workshops are not really able to vent my brakes clean no matter where I get to everything half-hearted … Now I don’t like anymore and just look for such a device for a normal price. The bay offers some but the selection is great my know how rather modest … what concerns the selection t. Maybe you have one at home and immediately a recommendation. Thanks to all the ventilators Greeting Stumpanski
