setup was a breeze and it works perfectly with my homekit. grohe stuff is usually pricey but the build quality on the sense is way better than those cheap zigbee sensors you find on amazon.

Tbh I was skeptical because it looks like a ping pong ball but the tech inside is actually pretty cool. The app is super intuitive and the "face drive" feature is hilarious. I've used some of the bigger Sphero models before and while this one is obviously smaller and has less sensors, it's way more portable. Great value for under $50. Only downside is it gets stuck on thick rugs so keep it on hardwood or tile!
