I've long since abandoned that whole Paleo thing, but the Instant Pot still makes great meals. I don't need a crock pot in addition to this. It makes amazing pulled pork and carnitas. I can throw a whole chicken in there and have it falling off of the bone in less than an hour. I can brown beef in it before adding other ingredients for a good stew or chili. It makes really good hard-boiled eggs (though I've recently discovered eggs in my sous-vide and will never cook them another way). I don't know how the Instant Pot brand compares to other electric pressure cookers, but I'm 100% satisfied with mine.
I liked it so much that I bought my parents one for Christmas two years ago and upgraded mine from the previous model to the newer model on last year's Prime Day mentioned in the article. The newer model solved my one gripe with the previous model (setting the lid on the counter was awkward when taking it off).
I recommend these things to everybody. Whether you enjoy cooking or not, the Instant Pot makes cooking meals easier.
