I was in need of kinda a 'bigger' cart than I had in my menu. The shop it is used on is being used by older people so the floating cart really helps make the cart easier to spot. And with the animations options it is easier to understand that you put something into your basket.
Also it's working very easily and nicely, no hard configuration settings and the settings panel is easily available in the customizer and the available features are all in all very satisfying.

Two things I would like them to improve on to make it even better (for me):
- easy translation management inside the plugin to change the wording without having to install a translation plugin (if your site isn't multilingual an easy translation page to put your native wording in would be super-useful)
- an option to change the loading icon from this kinda piggy-bank to something else (maybe there is an option and I just didn't find it so far)

Those two things don't stop me from giving this plugin 5 tacos, though because it's easy, straight forward and doesn't slow down your site.
