Granbo 1L Jewelry Cleaning Ultrasonic Machine 40kHz with Digital Timer and Degassing,110V Digital Ultrasonic Parts Cleaner for Denture Dental Oral Irrigator Parts Glasses and More

One of the most valuable machines in the shop! Great quality machine that does an excellent job cleaning so you don’t have to. This size works great for me and my uses. it is as noisy as a bee hive but all ultrasonic cleaners are. Just wear some good noise canceling headphones if you’re working around it. Did some rusty injectors with evapo-rust and they now look new!

I really enjoy the size of this ultrasonic as it fits all my jewelry and personal belongings. I do not use it for any larger items as it is only 1L but it is perfect for all my use cases and it fits very well on my counter. Easy to use interface and not too noisy. Probably don’t want it nearby you while sleeping though

Spacious and powerful, this is working very well in my workshop. I've been cleaning gears and oil coated parts with Simple Green. Also polished up some stainless with amazing results. Some comments say it takes a while to heat up, which is does. I just turn it on and let it warm up while I prepare parts and it's usually to temp by the time I'm done. It's also not too noisy. I can run it in my workshop and not hear it much when I go to the next room. And I can easily have a conversation or listen to the radio with it running two feet away. So far, used 3-5 times/week average for 30-60 minutes per session, it's doing well. I decided on this model based on product research and brand name. Also, I opted for one size bigger than I needed, which turned out to be a wise choice. Go a little bigger for a few extra bucks because you'll find all kinds of stuff to clean.

I am very happy with this instrument cleaning machine. I work as a manicurist, and this is the best instrument cleaning machine I have ever tried.

Final review and update: 11/14/2024 * Random snap buzzing sound for split second if left unattended and plugged in. Initial impressions: Right out of the box, the AC power cord & socket had a weak contact (both the cord itself and the inner inside of the socket) when i wiggle the power cord it would randomly loose power. So I had to remove the bottom panel (outer 4 screws) to tighten the power connectors (red & black), ground wire (green) was fine - its not a big issue for me but i can imagine that might be a huge disappoint for those who do not know how to fix electrical appliances. Features: * It does have a real transducer, strong vibe rhythm (noise is part of the functionality) * maximimum 30minute timer. * Degas (3 press on ultrasonic button) Cons: * A bit noisey but thats how it suppose to work * No OFF / ON switch * Looks kind of like industrial style, but really not bad for a small footprint. * power cord could of been a right angle, take up less space but you can purchase it separately, its just a standard computer power cord. Summary: Hopefully this will satisfy my need and hopefully it will last, it is strong ultrasonic with 30min timer it is way better than hose knock offs that only has 8min.

Works great, commercial quality. Used for my husband’s small engine repair business and works great

It’s a quality machine but alas, it doesn’t do what I’d hoped, cleaning sterling flatware without the polishing. There’s just no getting around it but I had to try!

The first unit arrives and was noisy and might have been damaged during shipping. Within 3 hours of reporting the problem the seller contacted me and immediately shipped a new one. Service of this level is practically unheard of these days. The replacement unit works fine. P.S my wife confiscated it to clean her jewelry. It does a great job.

Lasted 6 months then started burning and nearly caused a fire
