Ask whether the problem already annoys you
If the problem is real and recurring, the product has a much better chance of surviving the first-week novelty drop.
That is the simplest filter you can use before buying almost any Amazon gadget.
Check how much routine the product adds
A gadget that saves effort is usually a better buy than one that creates a new routine you have to maintain, unless that routine is something you actively want.
This is one reason broad-use tools usually outperform more niche kitchen or lifestyle gadgets.
Buyer feedback often reveals the truth
You do not need reviews to tell you whether to want a product, but they are useful for spotting the compromise points before you buy.
That is often where you learn whether the product is genuinely strong or just easy to sell in a thumbnail.
