it is a fantastic machine and does a great job of bringing most of my motorcycle parts back to like new. You need to use a the right ultrasonic solution with this for it to work.

not ideal in a busy workshop as you have to remember to turn the heater back on every use

Did the job great, but I ended up with another brand as this one had some of its pixels missing in the digital gauge. Shame as it worked perfect & if I could have got hold of the seller I would have been happy with a discount! Being Amazon I couldn’t contact the seller directly

I've had this just over a month now. I use it for "deep cleaning" xbox controller shells and PCBs as part of refurbishing them. As such it's had a fair amount of use. Generally I've been happy with it and it speeds up the cleaning process no end. Good points are that it seems reasonably sturdy and seems to clean well. It's a bit noisy but no more so than others I've seen. The bath gets up to temperature reasonably quickly however that's where things go a bit awry as the thermostatic control, on mine at least, is next to useless. I certainly would not leave it unattended while heating. The only other negative is that the display is pretty much unreadable unless it's in the dark. this is no big deal for me as I use the same cycle each time and it remembers the settings. I'm glad I bought the 6 litre version as anything smaller would have been unsuitable for my primary use. It's quite expensive but compared to genuine "professional" units (Crest etc.) which cost more like a grand it seems reasonable value. I don't regret buying it.

Very good service , chosen a good size , very happy

Very disappointed to have to give this two stars, especially as it appears to have done an okay job on my first days' cleaning. But that's why I went for a more expensive cleaner.There are two significant issues with this product. The first is the lid, which recesses and then has a further recess in the middle. This costs roughly an inch off the Internal space. If you have solid objects 5cm high, you won't be able to put the lid on properly, despite the basket depth suggesting 7.5cmThe biggest problem though is the safety. The manual advises against continuous running for long periods and I worked my tests up to 8 minute runs, with at least 10 minute gaps between them. At the end of my tests I noticed a small puddle of water underneath the unit (lid was on, unit was not moved once tank had been filled to 1cm under the max line) and the back of the unit felt damp and when I disconnected the power lead (which I do before opening the unit) I found water on the plug. This might signify a leak, or Simply be because of vents which are pointing down -straight at the plug-Since the product could cause an electrical fire I don't think I can use it again, but I may try once with some tissue between the vent and plug (to confirm if that's the source) and I may attend a run with the lid completely off. But as of now, my initial review is just disappointment.

OK what is there to say about this type of machine, hopefully it is a given that it works, so I will say a few things about its functionality.First off it was extremely well packaged. No damage and nothing missing. Instructions were as we have come to expect from stuff from Chinese manufacturers. Basic and in passable English.Two things that did surprise me. Firstly how fast it heated up to the temperature that I initially set (45 degrees), using water straight from the tap so whatever temp that was. Other reviews were stating it took forever to get up to temperature but not in my case. I can't say how long it took but not long! As for noise, then I was also expecting it to be noisier than it was. Bearable, but I wasn't in the room with it whilst it was doing its stuff. As for results? Well for the first attempt I used a mixed bag of things like steel watch strap, gold bracelets, jewellery etc and just using nothing more aggressive than clean water with a quirt of fairy liquid in it, then the items came up clean. Particularly the watch strap that had ten years of accumulated grime in it, then great results. Am I happy with my purchase, well yes at the moment. Nut I have only used it a few times, so the real test is how long it last before it breaks down. If it breaks down.

I bought this ultrasonic cleaner specifically because of its transducer design and its heating capacity. I have used it to deep clean my heavily egr gunk contaminated swirl flaps and the injectors to my BMW E60 520d. At 60 degrees Celsius and full wave cycle and a good quality ultrasonic cleaner it worked like as you can see in the photos to strip all the dirt on 16 year old injectors at 171k miles. Honestly they looked like new after the clean and despite being a chartered mechanical engineer and having studied metallurgy including doing research I would struggle now to identify the age or mileage these injectors have seen and done. The photos speak for themselves - what an outstanding end result. Next will be my Ford Focus injectors and the Shimano Ultegra chain set ! They do a 30l version which is pricey but might be a great solution to heavily caked egr gunk inlet manifolds. I don’t delete egr valves but rather clean up after them as they help heat up the engine quicker and keep my cars within the emissions standards on NOx and soot build up on my dpf.
