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.
This is one of my 9 month old grandsons favorite toys. The gears spin freely and he’s learned quickly to flip it back and forth and watch the gears spin. There’s no suction cup on so I’m not sure why suction is something that’s rated here. For teething- meh! But it’s a wonderful tactile toy for children that doesn’t have some electronic noise.
