Home Trainer Wahoo Kickr Core 2

Good morning, I would like to purchase the Wahoo Fitness KICKR CORE 2 roller, but I have some doubts about it.

On Amazon, this version is priced at €399 including shipping, while on the Wahoo website it costs €450 including shipping.

Amazon: https://www.amazon.it/gp/product/B0FLQDCR7X/ref=ox_sc_act_title_1?smid=A11IL2PNWYJU7H&psc=1

Wahoo: https://it-eu.wahoofitness.com/devices/indoor-cycling/bike-trainers/kickr-core-2-zwift-cog-and-click-buy

My question is: is the only difference between the two products the Cog and Click, or are there other reasons?

Thank you.
