I have had one for 3 years now. I had a hard time setting it up and getting it going. The first one did not work. It did not freeze the food. I sent it back and got another. I could not get a good seal on the pump. I ended up getting 3 different pumps before I could get it to work. I have not had any problems since except that the pump failed after 3 years. I have a new pump that does not seal as well and so the pump runs hot and at higher pressures.
I have FD a lot of different foods. My favorite is raw eggs. The medium size lets me FD 72 eggs in one run. Also shredded cheese and diced ham. Fruits and vegetables FD the best. I now have celery anytime I need it, same with mushrooms,blueberries, apples, and cranberries. I have FD ham and bean soup, which is really good. If you have a favorite recipe, you can FD and enjoy when you want. Fats do not FD well and will go rancid before to long.
I bought my FD for 3500 dollars. I have spent maybe 200 dollars in oil, a few hundred dollars in Mylar bags and oxygen absorbers, as well as mason jars. In the long run, it is cheaper to FD my own food. The problem I have is storage. The Mylar bags take up odd space. It also take time to cut up and prepare the food. Dicing the ham takes me between 2 and 3 hours. Same with apples, celery onions and such. So there are pros and cons. The Harvest Right company is good and will help you with any problems. They are a solid company and I recommend them.
