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. First off, the 10L capacity is perfect for larger batches – I can fit multiple pieces at once, saving me tons of time compared to smaller units I've tried. The 240W power combined with the 40kHz frequency creates powerful cavitation that blasts away dirt, grime, and residue effortlessly. I cleaned some heavily tarnished silver jewelry, and it came out sparkling like new after just a 10-minute cycle with the heater set to 60°C. The degassing function is a nice touch too; it removes air bubbles quickly, ensuring even cleaning from the start. The build quality is top-notch – the SUS304 stainless steel tank and basket feel sturdy and durable, and I don't worry about wear even after daily use. The digital controls are intuitive: adjustable timer, heater, and power settings make it easy to customize for delicate items or tough jobs. Plus, it's surprisingly quiet for such a powerful machine, which is great for my home workshop. Overall, this ultrasonic cleaner has made my hobby so much more enjoyable and efficient. If you're in the market for a professional-grade unit at an affordable price, the Granbo 10L 240W is a must-buy. Highly recommended!

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 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.

It works well and cleans carburetors really well in the right solution. I recommend you put hot water in. Do not use cold water!!! It will take forever to heat up. Also, the lid works but I decided to put some cooking aluminum foil over the top of the lid. It really helped a ton with heating up the liquid faster. So, if you're having heating issues with this, please use hot water, even warm it up a little on the stove if you can, and cover the lid with aluminum foil. It will work perfectly after that. Noise level is fine, it's actually quieter than my smaller one from another company.

This thing works WELL. It is a little loud with the metal on metal buzzing, but leaving the lid off helps. I ended up putting Plasti-Dip on the basket handles to quiet it down, and foam rubber tape on the bottom of the lid edge. Now it works great and is a LOT quieter.

Works great for cleaning my resin prints
