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.
the amazon box came good but the oxyclone box came with 2 holes and then the logo on my clone was peeling off and not sticking. still kept going forward with it. then one of the air stones is not bubbling. but i really needed this asap i am trying to use the half with bubbles since i have to kill my mother plant. will update review once i see if some cuttings make it. stuck with a diy looking cloner with out that pretty logo of yours. :(
