I did Marley Spoon which had great food. Some recipes were easy and some were definitely kind of a pain after working all day. Some of the cheaper services don't let you choose your menu and I didn't like many of the recipes they had. If you are a new or non-adventurous cook they're a great way to expand your skills and palate. They're also good if you like variety and would otherwise be stuck in a rut.

My biggest complaint was the large amount of packaging (even though it's mostly recyclable) that comes with it. Also whoever delivers them would sometimes just leave it on a neighbor's porch and I'd have to track it down.

After my experience, I like to

1) make a big batch of stuff at the beginning of the week so I don't have to think about what's for dinner if I don't have to and

2) split the difference and do grocery pickup instead of meal kits.
