Does the iCracked Ultrasonic Cleaner work?

I used to buy ultrasonic cleaners for our company. Does it come with built-in heating? That type are particularly good, over those that don't have it. The key thing to look for when buying an ultrasonic cleaner is not just brand or build quality or materials. You also need to check if the product is supported with spare parts availability - especially the sensors as they are near-impossible to get hold of at anything like a reasonable price. Now, the single most important thing to look for in an ultrasonic cleaner, is quite surprisingly, its size compared to the parts you are putting in there. You need to match the cavity size to the parts size EXACTLY. If you think bigger is better, you'd be wrong! The effectiveness decreases considerably to almost nothing when you have tiny objects inside a large cleaner. Most buyers do not take this into consideration & blame the product or the cleaning solution, etc.
