I'm Amazed that you are requesting a review, I have spoken to you twice now regarding the free bottle of carb cleaner you say every machine purchase comes with and yet I have never received mine, yes I am aware that 1 litre will not suffice in a 22l tank, but that's not the point here, Do not offer customers incentives that you have no intention of sending out! It's the small details that matter here, get them right and you could gain a customer for a long time here, If you cannot achieve such a small gesture, how do you think that makes me feel about your reliability if something went wrong with the machine!
