I've done Freshology off-and-on. I usually wait for one of their special discounts because it's so expensive. The best discount on is their Black Friday special (the day after Thanksgiving) where I usually sign up for six weeks starting delivery in January-February. It's great to have fresh fruits and salads in the middle of winter. The food is really very good - the best of the diet meal programs I've tried so far. It's almost Paleo, with mostly proteins and fruits and veggies. The mini-snacks are great. I wish they had a vegetarian version though.
On the "dislike" side (besides the price), I get really annoyed with their hard "Celebrity" sell. Their website looks like a tabloid page, and I personally don't buy things or do things just because some Hollywood celebrity endorses it. They should get rid of the celebrity endorsements and lower the price. Another annoying thing (which can't really be helped) is all the packaging involved in the delivery (unless you live in California). After you unwrap the huge box, you have to dispose of all the gel packs and tape and plastic - everything that keeps it cold. And hope that the Fed Ex people didn't drop it or tip it upside down. With delivery twice a week it's a lot of stuff to put in the trash or recycle bin.
