Sometimes when I click Aliexpress Link it does not take me to the exact product on Aliexpress?

If a product shows "No Orders Data Available" then the Aliexpress button will take you to a search page and not to the EXACT product. The search page that this product takes you, shows you many similar products and most of the time that will be the case, unless the product title is very specific (like using a model number or brand name).
