A Game-Changer for Cleaning! I've been using the Granbo Ultrasonic Machine 10L 240W for about a month now, and I have to say, it's exceeded all my expectations! As someone who tinkers with watches, jewelry. I needed a reliable cleaner that could handle a variety of items without damaging them. This machine delivers on every front.

Cleaned my diamond ring sooo well. Easy to use . not loud at all. Instructions come with straightforward directions. High quality. Easy storage. I like the size I purchased so it’s easy to store away

Bought this to upgrade from the smaller, plastic ones I've had in the past. It is a much better machine than those, and the price was good. No leaks, fits a lot of items so you're more efficient/less likely to waste solution. I do wish it had a proper drain, but I think that's limited to the largest offerings. It's also very noisy, and a rather unpleasant noise at that, but for the cost and results it gives I'm not unhappy at all.

This is my first ultrasonic cleaner and I’m pleasantly surprised my the results. It’s able to really easily clean my glasses and my watch. It gets to work in seconds and it’s easy to set up. It runs fairly quietly and has plenty of room in the basket!

This is outstanding. I’ve used other ultrasonic cleaners but this has a large capacity and great features. It’s quiet and everything comes out sparkling clean. I’ve gone crazy cleaning everything under the sun that can go in it. It’s actually exciting when you see how clean things come out. My reading glasses are now spotless.

This is great! My wife had been telling me for a while that she wanted to clean her rings, and this is the perfect solution. It's very practical, I highly recommend it.
