I bought this and used it for the first time two days later. Got like 3 hits in before it started to clog and spit hot oil into my mouth. I was told there was nothing they could do about it. This is my 3rd or 4th defective product I've received from these people. Was coldly told to contact the manufacturer myself because it was passed the allowed 48 hour return time. I emailed them 4 days ago and haven't heard back. Other reviewers have stated this is an issue.
