I have the Vacmaster VP215 and got it about 10 years ago. I have replaced the oil and keep it clean, but use it for much more than household needs. I feel that it was one of my best investments. I do many dry goods like flour and grains, bulk spices, powder milk. I tend to buy everything from wholesalers and in bulk and keep food spoilage to a minimum. The professional looking packaging and labeling helps to support business growth, even for the small guy that just wants to do this more as a hobby. I very sound investment in my opinion.
