I would include the links to the item you are reviewing so that it can be purchased or looked at by other members. Might assist with people being able to view the item in more detail outside of a review/opinion piece
When there are many vendors offering the same product, I do not include links as that may be seen as favouring a vendor. My preference is for people to choose their own vendor. I do include were they can be found. Not hard to find the sites using DuckDuckGo. For this item, ther can be found on AliExpress, eBay and Amazon.
Correct, a lot of effort does go into a review, and no one has an issue with that or your reviews. A good review will also encourage discussions around the item itself. The points you made in your response to
@Razor Burn don't really address his comments though. A review is not going to fix having to get the item replaced due to damage in transit because of poor packaging or spending a few months waiting for an item. Many people have bought from a seller and had items arrive and then when they put in an additional order later, the items never show up or appear 6 months later.
Purchases would experience these problems much less if they could and would read good reviews from people with first-hand experience.
Again it comes back to the vast majority of cheap items are poor performers, with the obvious exceptions being this brush and stuff like Gold Dollars, Titan razors, Yaqi gear etc.
Again the need for good reviews from people with first-hand experience.
Side note: if you want to give some budget gear a crack, I recommend
