I bought one some time ago and have rarely used it since but, on the occasions I have done, I've been impressed with the astounding difference between freshly cold-pressed oil and the so-called cold-pressed but certainly NOT fresh oils one might buy in the shops.
FYI Kyle, I use a Samson 6-in-1 juicer with the optional oil extractor attachment. It's made in Japan if I remember correctly and is linked to the similar Matstone juicer. I'm sure you'll find all the info if you Google it. I believe the attachment was originally for creating homemade toasted sesame oil as it can somehow be rigged up to heat the oil sufficiently. But, I've found it to be perfect for making all manner of beautifully fresh, cold-pressed oils such as borage, sesame, flax etc. Obviously, I wouldn't ingest these anymore but for oil pulling (or as skin moisturisers/cleansers) they're be very useful!
