The unit is fine and other than being a little noisy it works well. The communication and shipping were terrible. They only used a single tracking number for about 5 packages and of course when the first one arrived it reflected that they ALL had arrived!! Most of the packages came from China or somewhere and took forever for them all to get here… Made me a little nervous as I hadn’t done business with them before!

Well I’ve been using the machine off and on since I received it and so far so good.what I did not like is I did not receive the lighter adapter.I had to purchase this from Amazon.and it did say it was included.
