The products, that has been shown above, aren’t chosen randomly. We have considered several criteria before assembling this list. Some of those criteria are discussed below-
- Brand Value: What happens when you go for a not-so-reputable brand just because the price seems cheap? Well, the chance of getting a short-lasting product goes higher. That’s because the renowned brands have a reputation to maintain, others don’t.
World-renowned brands try to offer some unique features with their products that make them stand out in the crowd. Thus hopefully, you’ll find one ideal product or another in our list.

- Customer Reviews: Like ratings, customer reviews give you actual and trustworthy information, coming from real-world consumers.
- Seller Rank: Now, this is interesting! You should get a product that is trendy and growing in sales. It serves two objectives. Firstly, the growing number of users indicates the product is good. Secondly, the manufacturers will hopefully provide better quality and after-sales service because of that growing number.
- Value For The Money: They say you get what you pay for. Cheap isn’t always good. But that doesn’t mean splashing tons of money on a flashy but underserving product is good either. We try to measure how much value for the money you can get from the product before putting them on the list.
