I love this little guy. His shape is really pretty and he is easy to take care of. Just a little water per the apps recommendations. Haven’t had any issues with pests.

Definitely a cactus worth having if you like succulents and cacti or specialize in caring for those! I found it underwhelming as a lover of indoor tropical plants, but she is nice to look at and plays well with other succulents!
