I've noticed Density High Lifting is very popular these days. What is the typical price range?

Hello! Lately, I feel like my skin elasticity has dropped significantly, so I am looking into radiofrequency lifting. Thermage is too expensive to afford for regular treatments, so I looked into domestic devices and found that Density High is super popular these days. I am interested because I heard it has a cooling function that reduces pain and is very effective, but since no one around me has tried it yet, I am posting this question.

What I'm most curious about is the approximate price range. I know it varies greatly from clinic to clinic, but based on 300 or 600 shots of Density-High, how much should I generally expect to pay? I've noticed many mass-produced clinics running promotional events, so I'm wondering if it's better to avoid places that are too cheap. Also, for those who have actually received Density-High, please share your honest opinions on whether the skin around the jawline and nasolabial folds definitely tightens, and whether the cost is worth it considering how long the results last!
