overall brilliant, I brought this to clean my bike components from chains to cassettes etc and does it perfectly, i put 1 cap of degreaser to 2ltrs or hot water and it melts grease and grime off. I_e read reviews where people have said that their heater broke so I just put hot tap water in mine and don_ use the heater and when it_ cleaning it causes the water to remain heated anyway. When researching ultrasonic cleaners there would be videos of the grease coming off the components as soon as they start it and I was very sceptical and thought it was sped up, but my personal experience is it_ true as soon as you press start you see it straight away the grease coming off. If you purchase a 3ltr it only holds 2ltrs of liquid
