Havn't used it yet but it is very well made. As it should be for $109. It can be purchased for, i believe it was $68 with 2 needles & no carrying case. The needles that come with it are 5 1/2" closed tip perforated, 5 1/2" open slant tip, 5 1/2" fine tip needle & a 5 1/2" jumbo size. As per the picture below, the standard tip is placed inside of the jumbo tip. Its big! The only plastic on it is the barrel. It is a "50ml food safe unbreakable polypropylene barrel, and FDA approved rubber O-ring." There is a "unique dial setting which allows a precise amount of marinade to be injected with each squeeze of the handle." The settings range from 1ml to 5ml per squeeze. It is made in the USA & all parts can be replaced. 1 year guarantee. Looks good.
