I have been subscribing for only 2 weeks (6/$60). But the meals are good enough. It is a bit expensive, but it is healthy (gluten free, low carb, high protein, high fiber, etc.) and very fast (around 3 minutes). Most importantly, some of the meal actually taste really good, while others are decent - way better than fast food.
I would actually give it something like 4.5 stars because of the cost, but seeing how it has really low reputation undeservedly, I thought 5 is appropriate.
