The air regulator of RevoLine air compressor was over because the thread was pulled out. Well, you do not get a lot of pressure regulator for professional compressors but for this DIY compressor purchase price 120th This pressure regulator, even with pressure gauge for any subsequent exchange .... difference to the "naked" pressure regulator was only 1..deswegen ordered this, but with pain, because the purchase price is 9.95 ... final price incl. Shipping to Austria was 25.07, ie shipping costs are 150% higher than the purchase order value, that hurts, so 2 star deduction, because that's rip-off, unfortunately I have the part needed, works very satisfactorily, shipping was fast, there is nothing to complain, except total NEPP during shipping ... the usual 9.95 I would have anyway swallowed without comment, but you're gonna get the part afloat doorstep delivered and must not be overburdened with suburban retailers (which is, never heard, as can I do not help you, unfortunately, ... etc ...) to grapple .... CONCLUSION: The shipping costs are an absolute impudence and pure NEPP
