To calculate the overall star rating and percentage breakdown by star, we don’t 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.
Normally when something is advertised as pack of 5, it means you get 5 units of the product, with the product being the collection of the breadboards, the module, etc. In this case they meant you get 5 things, not 5 of each thing. That's okay, I suppose, considering the price and I will amend this review when this is cleared up, I expect this listing to be amended. The power module had horribly bent pins, not just bent inwards but also towards each pin. I think I was able to straighten them out, I've noticed pretty much everything else was bent or crooked. Very bad first impressions but it does function after some work. You get what you pay for, so four stars because of the low price.
