If your conversion rate is below 10%, then your issue is most likely the listing itself.
The images aren't too bad, but I would try to have the copywriting re-done by a native English speaker. There are grammatical mistakes that may be turning off buyers.
The other challenge is that there's almost a "quality" war. Just about every competing product has either 4.5 or 5 stars, so buyers have to focus on other elements to make a decision. Unless you have a differentiating factor, they will likely turn to either price or quantity of reviews when making their decision.
You don't want to compete on price and I wouldn't recommend trying to get fake reviews, so you should try to focus on ways to differentiate your product. It'll be tough since this is a fairly standard item, but you should spend some time trying to figure out if your product is different / better in any way.
