This is my first smart cupping tool and I am really impressed with its power. The instructions provide most of the necessary details, but I still had to try it a few times to get used to it. Here are the parts I like:

What I like:
Powerful suction: Even on the lowest setting, it is strong enough for my needs. A few minutes per spot is enough to get the whole sha out.
Portable and convenient: It is easy to take with me when I travel and I love how effective it is.
Smooth operation: All the buttons work smoothly.
Oil-operated: I like to apply oil before using it and it works perfectly.
Things to consider
Default settings: There are 12 settings for suction strength and temperature. They are both preset to 03, but I prefer to set it to 01, which means I have to press the button 10 times to get it to work. I wish the default settings were the lowest or there was a decrease button; it would be much more convenient to go down through the settings instead of just being able to go up.
Limited access to certain areas: I find it difficult to use on my back compared to traditional cups, which have tubes that allow for stand-alone use. Also, some areas like the shoulders are difficult to treat because they are curved; traditional cups have smaller cups that can reach these areas more easily.
