WooCommerce Product Size Guide is our #1 choice for choosing the most suitable solution when building Nitro WooCommerce theme. The "size guide" is one of the most demanding feature, so we've analyzed this product really carefully comparing with other ones on the market.
In our case, we've integrated it on almost 12+ ecommerce niches of Nitro theme and all of them perfectly matched our needs.
Thanks for making this product, guys!
Cheers,
Tony from WooRockets Team
