[personal UX/UI review] thought on displaying product images on websites

<case: product page for Nest Cam >


<case: product page on Amazon>


<case: product page on Amazon>

positive: Can see how big the items are intuitively

reason: Putting a universally recognized size standard object such as a deck of cards, coins, silverware, etc. next to a foreign product helps viewers' understanding of the product size.  Also, if the product can be placed at a context such as a hand or an arm, that would be a bonus.
