Things I liked:Seems to be made from quality material. Easily attaches. Gets the job done. Things I would have changed:Being a complete novice, an instruction book would have been nice. It came loose in a box with other items I ordered. Made me wonder if I bought an open item someone else returned. What others should know:I had to learn how to use it by reading other information on the internet and from YouTube. Don't be in a hurry to fill your tank...slow is your friend.
