Wonderful product! I used it to clean the grease and grime from my stovetop and over-the-range microwave and I plan to use it to clean the grout in my kitchen and bathroom tiles. I like how it comes with different attachments and batteries are included. Even though the packaging and instructions are in Chinese, it’s not even necessary to read them. It’s easy to figure out how to work the device on your own. The only complaint I have is that it’s noisier than I had expected but it’s tolerable. Overall, this makes scrubbing so much easier with little effort! I wish I had bought this product sooner!
