To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Of all the COVID self tests that I used, this is the most cumbersome. Because of the packing: I bought the 4-pack, and it is not a box with 4 individual test kits. Instead, the same items are packed together, so you get one bag with four tubes, one bag with four caps, one bag with four swabs and so on. In addition, the "tube assembly" that comes with other tests – a tube, already filled with the liquid – needs to be assembled with this kit. You need to squeeze the liquid (from one of the bags) into the tube (from another bag) and get the cap from another bag.
Next time, I will try to get test kits that are ready to use.
